Sid Meier's Colonization Classic, Sid Miere"s Covert Action and Pirates Gold Plus Classic. I don't know how good the Linux port is but it has the logo for Night Dive. I thought even though they are a bit dated I should get them to support Linux porting on Steam. I hope they are good ports. I got Crusader Kings II last week to support Linux and I don't think that is a very good port. Hopefully they will make it better.
