Yeah Civ4 was good, but I haven't tried any of the expansions..
I wonder why it is we're never happy with the sequels, made so many years later? I mean the list is long...
UFO Defense, X-Com TFTD, Civ, Sim City, Covert Ops, Pirates, All sierra games... Starcraft.. Worms was a pretty good take on fuck.... what was it calllled... oh yes.. Scorched Earth!

Before that I used to love my Amiga 500.. I'm still trying to remember the name of this tank game I used to play, where people would turn into red bloody marks and go "splat" when you ran over them with your tank... ;)
Also loved this game, Into the Eagles Nest:
