It's far too linear for a free roaming game. Every time I play it I'm reminded of how much more fun GTA is.
I thought the wii remote would have made it more fun but its basically the same as a normal controller considering you just press Z to lock on to targets rather than using free aiming. Less enemies and removal of auto targetting could have made this game a little better.. but still pretty poor in comparison to GTA.
i never use the z to lock on to targets, more fun the other way.
