I have not gotten the game yet, but I'm more than happy to see the numerous shortcomings of the series vanishing.
Namely:
Door Animation (useless in the Remake for sure)
Poor control system (awkward even after a while)
Poor inventory system (not being able to drop stuff)
Poor targeting system (down, middle, up pouah !)
Annoying cameras (that can be discussed but I don't like the principle)
Lack of realism/logic (come on I surely can blow up that door with my shotgun !)
Weird 'action' (I remember hitting 'action' to walk 5 stairs...)
That's just a quick list, I'm sure I could find many other annoying points that seems (from what I've read) to have vanished in RE4, for our (players) greater good
The v2 of the game is too much like a RE1 retry to me, old manor horrors... That would have been annoying, it's refreshing to be outside in the great outdoors.
