RPGs (online or otherwise) are my favorite games. I also like action games but don't care for first person shooters all that much unless they are more of an action RPG than shooter. I sort of got tired of them back in the day before they went true 3D instead of the old school doom style way of graphics. But I will give any of them a shot that the story is more of a focus than the shooter part and isn't a game where you will want to throw the pc out the window because you keep getting killed over and over trying to get past one little spot.

Games I own

Myst Masterpiece Edition (wish I could atcivate as steam game)
Riven the Sequal to Myst (wish I could atcivate as steam game)
Myst III: Exile
Star Wars: Knights of the Old Republic
X-com Apocalypse
X-com Enforcer

Possibly more as I keep discovering games offered on steam I already owned.
