Simpsons games can be rather hit or miss, but the most recent one was pretty darn good.
It definitively taps into the show's most memorable moments, but in a rather crazy way. Crazy, but a very good kind of crazy.
It also taps into other games too. From Japanese games to some of EA's own. My favorite are the Homer levels.
There all pretty good except Marge's mob stages. Marge sucks anyway so let's not act surprised.
One of my favorite moments was when Homer and Lisa went into crazy Japanese Anime/RPG land. Plus the whole game had great cut-scenes to watch.
