Endless Space is trash. Endless Legend is the second 4x, it’s much better. You will get your money’s worth just by playing the singleplayer.
I find the game so great because no matter what, anyone can win. The game is balanced that way by being unbalanced. The developers have stated so. It’s so fucking random it’s ridiculous. But, each race has a specific way of being played and anyone can play the race. You can have 8 players on the same race if you wanted to.
Also, if you’re into lore and series and such, the endless series is pretty interesting.
I’d say each multiplayer game, at the end score screen, you’ll be able to tell a story of what happened. You can do that with other civs but it’s not as genuine really.
honestly though, don’t waste your money on endless space
