Well games now HAVE to have trophies. If I had my way I'd give a platinum trophy only, "you booted up the game. F*ck You Sony." Trophies should really be just abou the game, ie, completion, and platinum should be 100% completion. No B$ about doing stuff you wouldn't normally do.
I'd rather have trophies that are just blocked by cheats TBH, but its a nice idea. The only way I would be persuaded to do trophies would be a virtual home trinkey. A gold stopwatch for that GTA4 trophy laid on my coffee table would please me a lot more than a white/grey image.
