This game, this product is just beyond imagination. There are a lot to explore and a lot to craft. The story behind the game is truly one of its kind even if the conversations are boring, unique and interesting [hope they make a movie out of this one :)]
Let me tell you a bit about the game as far as I know:
✅1. Maps and exploring: There are 21 big maps which means 3 biomes (Forest-Swamp-Desert) with 7 different type(Abeyance-Antiquarian-Astrolabe , .....) with random procedurally generated that you can craft with Major Realmcards, also in each 21 maps you travel, you can change environment with your unique Minor Realmcards to whatever you want with Realmic Transmutor, they affect conditions of realms such as weather, gravity, creatures and so on, maybe more damage you do to enemies, maybe more yield and harvesting items, blood moon , purple sky , ...... Sooo There are a lot I mean A LOT to explore and see with beautiful details and graphics as you see in screenshots.
✅2. Crafting: As the story goes forward you reach new gears and items in the realms you travel to, so specific items in specific realms. also you can buy some new blueprints and recipes from traders to craft, it's like 100 or more items as I know to craft.
✅3. NPCs and Gathering+Fight: There are some NPCs in the realms, you can help them out with some matters like fight alongside them or craft their home, and then you can recruit them. The recruited person now can help you with gathering materials around (so if you give them a nice axe they will chop down all the trees around), also they will help you fight against enemies.
✅4. Fighting scenario: The fighting in this game is based on the realms cards difficulty and also the difficulty you choose for them before opening the portal. Plenty of weapons in game as you go to higher level you can craft guns, pistol, rifle ....

💠So in my opinion it worth to buy and you will spend tens of hours, exploring crafting, story .... Have fun and enjoy :)
