I didn't get the first or second one but to be honest I didn't hate it. I heard the servers can support 60 v 60 games. Must be a load of lag though.
I did enjoy the first game but could not bring myself to finish the 2nd.
Admittedly not as good as the first but I still enjoyed it. BTW there's a cracking ending.
I hope what I've heard of R3 being a prequel isn't true though. I've enjoyed the story and want it to move forward not backwards.
