I agree with Xam. At first I thought I could handle playing a game like Ms. Pacman with a 8 way stick. I mean, more directions = more fun, right? The thing is, when I tell that b!tch to go up - I don't want her ignoring me. This is what happens with a 8 way stick. Most people play 4 ways by rolling the stick. If your going left, and you want to move up, you roll the stick from the left position to the up position. If your in 8 way mode, she sticks when you roll the stick and hit the diagnol. The only way to get her unstuck is if you return to center and then press up. Usually this takes too long and your on your way to being a ghost turd, or ghost rape, or whatever it is those ghosts do when they capture the Misses.
On a 8 way
Frogger takes extra hops
Mario gets stuck on the ladder in Donkey Kong
Popeye has a hard time with the stairs
etc.
Either have a dedicated 4 way, or a convertible 4/8 way if you want to truly enjoy the classics.
