I only like realism in shooters with a proper cover system.
I like it in Vegas and Vegas 2. And hate it in Bad Company.
GRAW...just had really awkward controls. With better controls, I'd have liked it.
I even liked it in GTA 4 and Mafia 2. Then again, the amazing soundtrack really took all my driving cares away.
Basically, give me a proper cover system, and I like it. Give me one where I have to physically stand behind the object, without a snap-to cover system, and fuck it.
If you ever put realism in my RPGs, I will stab you, though.
