During race creation:
Pick
-Any but human, humans get Solar System, others get random systems, gonna get to that at the middle
-huge world (gotta get that quickstart)
-republic (20% research)
-Native to Metal planet (the worst type of planet AKA huge lump of iron, now you are native to it, getting 100% pop growth on it, and EVERY SINGLE OTHER TYPE OF PLANET EVER TOO, congratulations, you can now colonize every single planet in the universe without terraforming, which only increases the pop cap on non-metalic planets after terraforming)
-Transient (2-3x movespeed on map, it's ridiculous)
-Immaterial
-Quasi-Immortal (I don't remember which is which from these two, one of them makes so that any ship that gets boarded explodes [not that enemies ever board your ships though], immune to pollution and don't require food, the other gives 99% workforce instead of 33%. You are literally 3x better at everything than the rest of the galaxy)
-Ecoadaptative(Metal world is free and have the same effect, since you are also immune to pollution from the last two)
-Repulsive (you don't want no business with those dirty aliens, what are you? An heretic?)
-Cloaking tech (Gives 99%~ chance of first strike, what determines 99% of the outcome of the combat, since everyone get oneshot lategame)
Lots of finance and Research and ship attack, Farming, Industry and Trading is useless, ground/boarding combat is also useless, morale is unneded thanks to Quasi-Immortal.

If your solar system don't have 2-3 planets with gems/gold, restart, it takes 5 seconds + loading to restart the game.

Build a single level3 ship with front-left-right Regular sized lasers and back light lasers, one troop compartment (you need no more than 5000[minimum] troops to take ANY planet) and cloaking. It will take about 200 turns, or about 30bc to buyout, which you get in 20 turns or so if you colonize those gem planets. This baby can reck ANY civilization from the get go.

Search everything, [S]earch solar systems with your scouts, make more scouts, [D]ig discoveries (only way to get stargates afaik)

Once you get your level3 ship (about 40~ turn), send it to any enemy home planet, you can beat anyone, really. Remember to 'Engage System' before ending your turn

Once the combat start, there will be a big and bad space station, just park your ship on the opposite side of the planet, making sure your regular lasers are in rage of the planet, but not of the space station. The space station will send little ships, you blow them up in 5 of the 50 turns available to you. Now reck the planet until it have 1k< less soldiers. then hold enter until the 51th turn and select Invade. There you have it, an enemy capital and a space station. For undefended systems, just select 'destroy colony' and 'auto solve'.

When I was about to end two of the last 3 civilizations, they started some random ass voting to see who wins the game. They all together had 3k votes or so, I had 20k. I wish there was a option to ask them to ♥♥♥♥ themselves and just kill them.
