Lets see here:
Masters of Orion 3, yes a huge let down but now with a lot of fan support and modding, its actually quite a decent game.
Red Alert 3, yeah the game is pretty bad, the campaign is the only thing it has.
Spore, I was super disappointed with this game.
ST legacy, same thing with Masters of Orion 3, a huge let down but with mods out there they made it quite fun, my buddies and I play this once and awhile in a lan game using the mods, alot of fun.
Medieval Total War 2, yeah the overall strategy in that game was just really bad, thats why im hoping the new one coming out (Empire total war) is amazing, but not as laggy as the demo!
Hearts of Iron 2, not so much but hearts of iron I was just amazing, the changes in II made the game feel very different, took awhile to get a hang on it, now its an amazing game for me to play, cant wait for III.
