Quoted from cheesewhisperer:Will be searching to play original Simpsons and South Park before deciding to buy Family Guy.
Let me save you the trouble, You don't need to play those games first. Liking the theme doesn't always translate into needing to own. South Park is just not a very good game, and DE simpsons might be to simple compared to the games you're talking aboot here.
FG would be an easy choice there. Good luck!
