I just got my Wonka last week. It's on location now, but I did get a few dozen plays on it. The voice isnt too annoying. It reminded me of roller coaster tycoon. I haven't played a rct in a long time, so I maybe off on that.
Wonka is a little repetitive at the start. Like any game, the more you learn the better it gets. I do love it when he starts singing the creepy boat song and the playfield goes dark.
