Realism? Hah, good one. If the game was striving for realism, how many of the other design choices would be the way they are? That's the just excuse for apologists in any game. Criticism of RE5's no moving and shooting? Explanation: realism! Never mind that you can't walk and use a knife either....Same deal with this. If realism were your concern, shouldn't you be appalled that it takes more than a single bullet to put someone on the floor?
Sorry, but your argument is moronic. Trying to add a bit of realism to one area does not mean they have to go the whole nine yards. They're trying something no other FPS has ever done before, make the weapons and your armor feel like they have weight to them. This does not force them to make everything else more based in realism. Its all about design decisions and trying things that they believe will be fun, but a little different from what everyone else is doing.
The RE5 control argument...I'm just going to avoid it because I don't even like the series anymore.
