Rule #1 of Demos. Don't give time limits. Just give a small, completeable portion of the game that can be fully enjoyed by the public. Timed demos really just limit your enjoyment because you are trying to cram everything into a small amount of time. I know they are preserving thier game and trying to hype you, but honestly, just let me enjoy it!
With that out of the way.
DMC4 was pretty good. Nothing too special gameplay wise, although I loved reving up my sword. I'm still getting used to Y being the attack button, and the guns seem pretty worthless. Pulling off slick combo's is still as fun as ever, and it's one of the best games graphically.
Nero really isn't a big jump from Dante, and personally I like the change of character. The Devil Bringer is neat, and I am looking forward to seeing it's true powers, not these dinky throws and grabs. One of the best parts about games like DMC4 is that the further in you get, the more badass you truely become. It's going to be a blast having fully upgraded weapons and Devil Bringer, although to be honest the demos powers were pretty weak, but then again its a demo.
I also see no difference between the PS3 and the 360. They are pretty much the same, and controller preference will be your only divider. Although I will admit it is kinda weird playing DMC on an Xbox controller. It isn't bad, and it's very good, but you spend so many years with a Dual Shock in your hand for one series, it's bound to feel different no matter what.
I'm not getting the AAA vibe, not because it's bad, but mainly because I feel it really isn't doing anything that hasn't already been done in other games, or the DMC series.
It's just a very good game, and it offers a vast amount of fun to anyone who wants to enjoy it. I am happy that it is going to make the Feb. 6th release date, and while I'm not jumping out of my chair at this moment in anticipation, I can tell you that I will definately buy this game.
Predicting an 8.0 or 8.5 here. Possibly a 7.5 if the reviewer has negative pre-determined opinions of combo-based action games.
