A common criticism leveled at social games is that they are not, in fact, very social. After all, few Zynga games let you interact with other players aside from sending gifts or using them to power up yourself. Fun Park is one of the rare games to actually be social, practically demanding that you play it with, ideally, at least six friends. The game is so reliant on having friends that it provides you with three CPU "default" friends, because without any friends it is literally impossible to make any progress in the game. Fun Park gives you chat and in-game mail systems so you can make the experience even more social, but at the cost of making it completely uninteresting for a solo player.
