I played it for a little while last night. Strange, first few waves, it was like, meh, Prime is nuts for playing this all the time, then a couple more waves, then you start to chill with it, a few more waves, then suddenly your obsessed with its simple but suddenly engaging gameplay dynamic.
Cob cannon is ridiculously fun, and it puts the player back in the game because you have to aim (more like direct) and manually activate it. Of course, the fact that it's one of the most effective plants in the game, especially when you get a group of them, helps.
