Well theres a great rank up technique that works on R2 to get tons of points. The glitching really lacks unless you have a lag switch. But as a glitcher myself, I really like R2. If you played the first one and liked it you'll most likely love this one. It's a great game and I suggest buying it. And if your still a little skeptical go out and rent it

I rented it and i love the online play so many things to do :]
