I really, really enjoyed ZOE, but while AC2 I think had a lot of potential, the controls were to complicated (not hard, but not easy to master). The controls for ZOE, on the other hand, made it seem like you could be using a PS2 control pad to actually fly the ADA system... ZOE\'s downside is that it\'s a bit short, five hours, all told, but it\'s still really fun, and I\'m currently going through it again, on a harder level....
