Sins of A Solar Empire (PC)

This game is a brilliant RTS. I love it what with me being a huge Sci-Fi geek LOL!! You pick your race either Human, or Two alien races (can't remember the names!!) then you have to build an empire by colonizing planets in your system...then, you build ships/space stations and planetary defences. You can choose whether to ally yourself with the other races, or you can destroy them

Theres a ton of Mods you can download too...my fave was the Star Wars mod, Star Destroyers, Republic Cruisers, and X-Wings You can also get a Star Trek mod, which was first made for Homeworld 2.

I haven't played this online yet, and tbh, I don't think I will...the single player can last for days at an end, and thanks to the map editor, you can create massive galaxies to explore
