I'm incredibly excited for Resident Evil: Revelations, and I'm... pretty excited about Resident Evil: The Mercenaries 3D. I love Mercenaries mode in Resident Evil 3, 4, and 5, but I'm not sure about this stand-alone Mercenaries game. I hate to sound like a broken record, but my main concern is shooting controls. They sound like they'll work great in Revelations, but in Mercenaries, it looks like they have you'll switch to first person when you aim. I could be jumping to conclusions here, as I'm only going by these two short videos, but from the looks of them both, all the shooting is done in first person.
I like FPSs, but I generally enjoy 3rd person shooters a lot more. It bugs me to think that Cacpom may be changing the series in order to chase afte Call of Duty's success. Resident Evil is one of the last great 3rd person shooter series still going. I'd hate to see it change genres now, especially if it's just to keep up with current trends.
