All for PC:
ACW: The Blue and the Grey by AGEOD: Played the tutorial and never played it since. Heck, it's still on my computer. I liked it but never got back into it

Starcraft- Eh... never got into it. Plus the fact it was a ripoff off of Gamesworkshop turned me off nearly completely.

World of Warcraft: Got this because a friend said I should try it out... *yawn* lame, boring, generic. Waste of my time when I could've played other games or read a book. Most other mmo's like Lineage also give me the same feelings. The only good mmo's I've played were Planetside and WWII Online.

Madden Football: After the first 4 games it was boring. Playing against friends was okay but I smashed em every time. Still a boring game nonetheless. Basically sports games in general bore me.

Medal of Honor: Mostly the entire series got boring. Never played mp as CoD 2 and United Offensive were my favorite mp games.

Combat Mission Series (the first 3 games, CMBO, CMBB, & CMAK: All classics and I've played them quite a bit. But they are very time consuming and I play in spurts, especially the HUGE scenarios, thos take forever

GTA Vice City: Got this for my PC from a friend and never installed it, let alone taking it outta the box! And I don't think I'll ever load it up. In fact the GTA series is quite tedious and boring. Tried to get into it but the only fun was using cheats to cause everyone to fight and get the tank.

GalCiv II or something like it: Got this after hearing a LOT about the series. Was bargin bin so I figured it wouldn't hurt. Got really frustrated after a while and just uninstalled and never tried again. My next "classic" is X-Com tho I hope it works for Vista
