Sin's is a game my friends and I always come back to. Such a dynamic rts with so many ways to win.
The expansions are fairly priced and also one person having an expansion is enough to host an expansion game for everyone who has any version installed.
Great game. Awesome game. Runs like shit in late game even on modern hardware unless you keep things smaller and boring + the modding situation sucks a lot. Fun enough to still be worth playing. Hopefully someday they'll make a sequel to address some of these issues or someone else will make a similar game with better performance. Sins 2 is a thing but it's only on epic and I don't use Windows. We might get a steam release some day but until then I'm too lazy to pirate it.
