MrEco: You are probably thinking of Resident Evil 4 since Resident Evil: Umbrella Chronicles is a rail shooter where movement is never an option. And since it is RE4 you are almost undoubtedly talking about I should mention that you couldn't move in any of the versions of the game. The original version was on the Game Cube and they then made a PS2 port, and finally a Wii port almost a year later.
Sure must've been Resident evil 4 then. I'm not complaining that I can't move so much as I'm complaining that the fact that you can aim at the screen, which would arguably add more realism and a better aiming performance, is actually deceiving. Wii gamers all over the world are high-fiving each other as to how aiming at the screen is so much better than using a mouse, but as it is, I kindly disagree.
MrEco: Also, one last thing. Dead Space is an over the shoulder
third person shooter, so comparing to a first person shooter like Medal of Honor would be a huge waste of time since the controls are automatically going to be extremely different.
First or third person "looks" different but doesn't change much in terms of aiming in my opinion. It's the same crosshair, only (sometimes) positioned differently. Freedom fighters comes to mind... aiming works just like Doom or any other game. Anyway, that Resident evil I played was third person too, just like this Dead space.
soulgrindr: Of course, many people are now used to Dual-Analogs, so getting used to a new scheme can take a while. Though if you've ever given a new player a dual-analog FPS and watched them run around looking at the floor and ceiling the whole time you quickly realise that DA sticks aren't as intuitive as we think... we've just gotten used to them.
I sure hope you're right and someday we learn to aim a pistol at a screen as much as the developers learn to make it more smooth and less crappy... :)
