The multiplayer category allows you to create a LAN game, access the PlayStation Network to race players from all over the world , or check the leaderboards. One disappointing thing that I found about the multiplayer aspect was that I was unable to find anyone through the PlayStation Network. I'm not sure if that was due to a lack of players or what but every time I tried to join a multiplayer game I received a message that there were NO GAME SESSIONS FOUND AT THIS TIME. This happened to me over the course of several days, so it is some what a dissapointment if you plan on playing mutliplayer. I even tried filtering my search differently but was still unable to join a match. At the time of writing this I found someone else's complaint with this issue but on the Xbox360. This could be due to the fact that not enough people are giving this game a chance. It's a good thing that you have the ability to invite your friends into a match, as I played some against Oly. It was more of the regular game, however fun to actually race and destroy a friend. http://naildbiter.com/nVGgQ
