I'd much rather have a skeleton than a game but that might just be me.
I actually like the first one the best. It seems more like how a cheesyish commercial would be toned. The green-toned one gives off a weird air...as if I'm not suppoused to know what is going on. The orange red looks very nice but gives off this very mellow tone which conflicts with the skeleton's expression. At the same time....he is a skeleton so it sort of works. The red-speia has a little more "power" behind it but the skeleton's suit is too bright and makes that the main focus. The brown sepia is nice but makes me think of old times and not advertisements which try to be colorful and attention-grabbing.
My two cents
