BTW don't bother with DDO. I loved playing through most of the game but in the end it is a decision to shell out a *edited* ton of money or just do the quests enough times that you can "elite" on your own.
I am tempted to play Dawn of War.
And I do have to say that if you don't already own Civ 5 DO NOT BUY IT. Since the demo I have put in over 40hrs of game-play and I have barely been playing a week now... or actually its been exactly 1 week. If you do have it contact me and we should get a game going.
Another game I would recommend trying but not buying and this time I am serious on the not buying part is Nation Red. It is a good game for single player however certain parts are beyond hard. There isn't too much skill involved with the game however it can be fun. I haven't played online yet because you have to have a person you know who has the game, play with you.
