Using the helpers and plugins would probably be useful, but I don't know how using model view controller would work out with games. To me, it seems more difficult rather than easy to use cakePHP, but I haven't really tried it before.
I have tried codeigniter though, and I think the ideas behind those two are pretty much the same. I'd use codeigniter for a normal website, but not for a game unless I really understood how to use codeigniter
