I think RE4 was so great because it was a great blending of genres. At it's core, it was an action game, but instead of being like Devil May Cry, which was basically RE2 with combos, (fantastic game) they fused character action/shooter/puzzles into one game.
No title does exactly what RE4 does, but I get the same feeling of accomplishment with games like Souls. I felt Gears was certainly heavily inspired by RE4, same as Uncharted. In fact, part 4 especially the gun play feels like ND were playing RE4 while revamping drake's shooting.
Capcom might make it action heavy again one day, but in all honestly, that is probably going to just be DMC. This it the direction that inspires the team. That's what I want. To ask for the same thing over and over again is not seeing the forest from the trees. If we truly want a classic like RE4 to happen again, we have to let the team be inspirational. They've done something special here with VR and horror, there' s no denying it, at least let them perfect it before we ask for a return to form.
