I tried adhoc party PS3 with Wipeout Pulse back in Q3 2009 with good Ukrainian mate Nightark. It was when the first english varients of adhoc party that was slowly being released on the PSN store, the US one if i recall. 4players max in a room at time, just like Pure. Did find the gameplay alot more jumpier in adhoc mode in comparison to infrastructure mode. Just like Gran Turismo PSP also.
