I don’t think trust is at issue here. If the game sucks, don’t buy it! There’s millions of other games to play.
There is reason to hope Blizzard will turn around. Bobby Kotick is gone. Microsoft owns the company now. Say what you will about Windows but Microsoft tends to take pretty good care of the gaming franchises they own. I think a lot of AoE fans are pretty happy with how that’s going. I could be wrong though?
