dewtech: Perfect HUD. Nu bullshit info, only barebones what you need info, although the lower right menu could have been implented on weapons aswell (IDK how on crossbows, but on SMG-s and Pistols for example show ammo on some indicator on weapon or whatnot), but it would have been more work.
It actually looks a bit different still, but yeah, even then - the displayed digits only have slightly dimmed background to ensure they're always visible, otherwise it's about as unobtrusive as possible. I don't think weapon displays are more work as much as they quite simply would not work well with the setting.
I'm still a fan of relaying as much information directly trough the game or only display hud when it's relevant -
this is what Far Cry 2 looks like most of the time. When you shoot, ammo counter gets briefly displayed - so does health when it drops. Otherwise... Well, let's just say that
this is the map screen. Then Far Cry 3 added
this monstrosity. *sigh*
Edit: Who the fuck needs a crouch indicator anyway?
