I wait for MTW2 because EB 0.8 is still a Beta, otherwise it would be 1.0. Because a beta is not as complete as a 1.0 game, MTW will be my choice.

Otherwise, MTW will have bugs, too...so
I play the game that is released first (I think it will be MTW2 because EB is developed quite slow (understandable, because the team is not paid for it))
