Wow great ideas guys. I'm a little afraid to start making ideas up about a game we'll most likely never see, but I'll go ahead with it because I love thinking up ideas for games I'm interested in.
I love the spralling cities idea, with animals, explorable houses, side quests, and all that other stuff sounds great. I would have loved it if Stranger were more like that. One idea I had once that some may remember was to have it so Fangus could run around like Stranger, but more like that SUV animal in the SUV commercial. Does anyone remember what I'm talking about? In any case, it was this large, fuzzy, beast-like SUV/Buffalo hybrid. It moved around very fluidly like a dog, but also very hulk-like in appearance.
I would love it if you could crash into buildings and make either huge dents (big metal structures) or smash through it making a hole in the house (wooden houses). Enough hits and you could demolish an entire building/house/structure. Also, brick houses would take a few hits to knock down, and bricks would fly everywhere in the process.
See, I just love the destructable environments idea, and I want them to take it even further, except have there be HUGE cities you could just have a playground for platforming, demolishing, and just shooting up everything you see. What I wouldn't give to have that type of game. #1 reason I'm looking forward to the new Hulk game coming out this summer
Damn, I've hyped myself up for nothing
