Purchasing this game is entirely up to you. If all you play is GTA style games then you might as well give Saints Row 2 a try; you will get some entertainment out of it. The game offers a co-op mission mode that can be saved for the singleplayer portion of the game or if you like to test your skills vs. other online players, there are several multiplayer modes to keep you busy. On the other hand, if you've played through GTA IV and absolutely loved it, you might find it difficult to switch to a game noticeably inferior. Saints Row 2 is more about the "bling" and less about the gameplay.
