"I played the game entirely in first person"
I personally don`t think any game with an invisible weap in the 1st pov can be called a 1st person view. And as well imho, GR and R6 were exactly the same in this area. Invis weaps. Which as well blows. lol It was ok for R6s day. But I wouldn`t touch a GR game now unless it sports a weap in view.
