Tron 2.0 - A FPS game set inside computers from the early 2000s. There were a lot of great weapons in the game but I always went back with the Disc throwing weapon.
Homeworld 1/2/Cataclysm- An 3D space RTS series 1999/2000s. During the campaign all units made carry through to the next mission.
I hear some of the online modes are awesome but the story was a bust. I was looking forward to a good old Homeworld story but I heard enough to know not to buy it.
It's also one of those games that end up as discord competitive games, like a lot of fighting games. You kinda need to play against people who are really into RTS if you're gonna play it online a few months after release.
