I'm still not convinced by this....
I mean I'm not keen on how the characters look, I prefer HighPolygon model like, for example, the characters you play in Jak & Dexter or the more designed ones of Evil Twin.
In fact I think that with such an option, games lost most of the benefit they gained through their 3Disation (volume) while not getting the details of "old-school" sprites.
But all I want is to be convinced.
