TL;DR Don't buy it, if you really want a good arpg there are others to pick from.

Now for the in depth review

Dragonkin the banished is a arpg that's made by a small team of devs that managed to nail some important core elements of what makes an arpg good, but failed on a lot more. I will list some pros, cons as well as some things i have mixed feelings about.

Pros: - It has good visuals, its graphics are somewhat cartoonish but it leans more into the realistical side of things, personally I like it more than last epoch/poe1/d3 but its inferior to poe2/d4
- It has the best companion system out of all the top arpgs simply because in this game its free, you get your wyrmling early on, they look cool, you can equip them with armors, and they have some functionality as they will attack enemies or enhance your skills. On the downside you only get 4 companions to pick from, however its still early access so maybe in the future there's more to pick from
- It has a good variety of mobs given that we're in EA
- It has a good variety of skills and the grid system is pretty interesting as it allows for different active skills to be enhanced by the same support skills.
- the fights in this game feel satisfying, the feedback you get from killing packs mobs is good, it has that crunchiness to it, which is an essential part of what makes an arpg good.
- I really liked the prologue, it was short and on point, allowing you to preview how each class plays.

Cons: - The difficulty of the game is done wrong. At its normal difficulty setting the game is too simple, I picked the maximum difficulty for the campaign, and even at this setting the regular monsters were too easy, instead of 1 shooting everything I 2 shooted them, however the difficulty suddenly spikes to insane levels because of the elites in this game, not because of a certain mod they have or the high HP etc, but because they throw multiple packs of elites out of nowhere at you in mid and late campaign. I'm talking 5-10 packs of elite mobs with modifiers such as guardian which makes all the pack monsters invincible until you get in the radius of the elite itself, mods that can heal, mods that will spawn projectiles, some elites will be able to teleport, some will be immune to certain skills, others elites will be invincible until you kill the rest of the mobs first etc.. Now this wouldn't be an issue if you would only face an elite pack or 2 at a time, as you do in every other arpg, but when u have 5+ packs of them all summoned out of thin air during an ambush, the sheer number of invincible mobs + the healing ones + the shielded ones + the projectiles everywhere, all stacked together, make it virtually impossible to defeat that gang of elite packs early on in the campaign simply because you won't even be able to reach the elite you need to kill first, due to mob density, in order to disable the mod that makes the rest of them invincible, especially if they can teleport around etc. Playing on normal difficulty isn't gonna change this fact either since on max difficulty the mobs only have a 2.7x multiplier to hp/def/atk, so the only thing you can do when this happens is to just run from them or you can try and kite them 1 pack at a time but that will be extremely time consuming. Nothing here is done well or fun, they absolutely fumbled the difficulty of the game by making it too easy even on the max difficulty setting with random moments when they throw an insane amount of elites at you at the same time.
- Mob AI is hilariously bad. You can run around any pack of mobs while attacking them and all they can do in most cases is just chase after you without being able to attack. Boss AI is even more horrendous, every single boss I fought so far (3 in campaign and 1 in endgame) is static, they literally stay in 1 place and just throw random attacks which are easy to dodge, with a lot of safe areas in the boss arenas
- The loot in this game is done wrong. One of the reasons people play arpgs is for the dopamine hits they get from lootsplosions, because of the chance of getting a new and better item which will push their toon to the next level. Here the loot is as dry as it can get during campaign and early maybe even mid end-game. Basically every 10 levels you unlock the ability to get new tiers of loot (level 1-9 you get only common apprentice level items, level 10-19 you get common and uncommon apprentice level items with some hunter level items, level 20+ you start getting rares). Now this alone wouldn't be so bad, if not for the fact that leveling is also extremely slow in this game, because the max level is 50 here. This means that by the time you finish your campaign and you dive into the end-game you will be around level 18, which means that you start doing endgame with uncommon(blue) apprentice level items which is bad lets be honest, when in any other arpg by the time u reach endgame you already have full rare with some legendary/unique (orange tier) gear.
- Leveling is extremely slow due to the fact that they decided to go for a max level of 50 instead of 100+ as it is the norm in arpgs. Now to be fair, both the slow leveling process and the absolutely dry loot this game offers won't affect your progression throughout the campaign or early end-game BUT it does make the game feel stale to a mind numbing degree

Mix feeling: - The voice acting. Initially I wanted to put this on the cons list based on the VA of the lady in the prologue, but later on they have really good voice acting added into the game
- The city. While it has a lot of good features which are directly related to your character progression (you can unlock crafting, permanent passives for your character such as max hp, movement speed, damage reduction, all attributes, exp) there are some features that are useless early on and if you make the mistake of picking one such feature you can't undo it, and you will lose the point spent there. You get 1 point each time your city levels up, and they way you level up your city is by completing quests/hunts (end-game activity) or finding chalices in the world, but it takes a lot of time to gain 1 level, so those points are precious early on. For example I reached level 25 and my city is barely level 8, and to give an example of a useless feature early on that would be the treasure hunter upgrade which increases the gold you get, since there is nothing you can really use gold on at this level except for some very cheap crafting.
- The end-game (hunts). So how the end game goes is like this, you pick up a hunt from your main hub area, first thing you will have to do is to complete some objectives which are mandatory in order to progress your hunt, some of these objectives include killing mobs, doing puzzles, doing escort missions, protecting npc etc, some of them are enjoyable, but others are extremely boring. After that you are required to do a dungeon which is similar to rifts in d3, then you do have to close a rift (kill waves of mobs) and finally you get to kill the dragon. These encounters are long to very long (30+ min), loot is scarce and your exp bar barely moves up, but you do get to kill lots of mobs in the process without much issues.

All in all there are only 2 reasons I can think why anyone would try this game. Either you played every other notable ARPG, done everything there and you wanna try something new, or you're a huge fan of dragonslayer power fantasy. My prediction is that this game won't amount to anything as they got wrong so many core elements of an ARPG despite being in EA. They would need to scratch almost everything they've done so far and start over for this game to have a chance, at this rate this game won't be the next last epoch, they would need to be extremely lucky to even hit wolcen numbers. But I wish the devs good luck and maybe they will prove me wrong

Cool concept. Not there yet. Deeply boring "demo" pretending to be early access, seemed actively interested in wasting my time.
