Played some 4 player tonight and really didn't see all that bad of a slow down. Maybe a little bit noticeable at some really hectic times, but for the most part it is pretty good. I just wish they would enable an option to turn off the PERKS repetitive comments. If I had a way to play with out all the commenting from the characters, it would be so much more enjoyable. The first few rounds it is comical... but after playing a lot of time with this, I find the constant repetition of the same old 'wise cracks' getting stale and old. I know I'm probably the only one that feels that way, but it would be nice if there was an option to just play with the SFX only.
