I'll do a small amount of roleplay in most games I play (at least, those that are immersive). Just small actions that could be comparable to what a "real" person would do in that situation. Never do I shout, "FOR GLORY, WE MUST SAVE SKYRIM FROM THE IMPERIALS" or something like that. It's a light touch. Edit: A good example is the night time city in ODST, coop on Legendary. I'd be "leader" and we'd all make our tags military ranks and we'd assign roles and use squad tactics on the Covenant. But we weren't talking in military chatter or anything. It was just we'd cut normal talk down a little bit. Like I said, it's all for immersion. Edit 2: A better question would be "Do you role play in games with campaigns?"
