As much as I like Resident Evil and its characters I personally think he should continue with using characters from movies rather than game characters. He really stands out doing that. Though when you do use IPs owned by the likes of Disney you're walking on a knife edge. Though I am sure Dreamworks do not really give a shit. You know, use characters from How to Train Your Dragon, Shrek, Bee Movie, The Road to El Dorado(you and I both know Chel woke something in as lads)...
PS: When going into those animation studios as a producer, department heads are going to show you all the r34 of characters in their studio as a way of saying that there is no stopping shit like that and they should get used to it and don't bother getting peeved about. Though there is a threshold where you can get their attention though.
