GWG is one of the Wii games I keep coming back to.
Nice review. I do agree that most of the drones are useless, however the one that puts out extra firepower is quite handy in many levels.
Yes, a classic controller is a near necessity if you want to win a medal in many levels.
The one drawback I found it the certain sameness to the levels; one you seen the six (or so) major variations, you've seen the whole game. In many ways this game feels like a throwback to the old Atari carts, were you'd have oodles of variations based on the main game.
