I'd like to see resident evil go back to the old style, then perhaps you could unlock side missions in the new style. For me through Raccoon city really did it for me, the atmosphere created by a 'dead' city was un-matchable and un-beatable. I know ORC is going to be new style old location, which will be great to see and I'm looking forward to it. How about a old style, old location, new graphics, I dare say they could fit a whole lot of raccoon city into a new game. Make it dark like really dark, we've had things like the zoo on outbreak and the hospitals.
This could be further enhanced, how about a school or nursery that would be gruesome (the latter could cause some problems mind) with the new consoles you could fit the whole of raccoon city into a game. Even throw in a side mission in the police station, there are plenty of everyday life situations that could be expanded on...
Supermarkets, airports, trainstations, bus stations, country parks, kids playgrounds, afore mentioned schools, colleges, big business buildings, underground tube stations, more of the zoo's, hotels, banks, I could go on... All these things could be turned into horrific raccoon scenes and could be included and made truly awesome.
That's my quick opinion anyway!
