No, Voltorb Flip really was amazing. Don't be mad that you couldn't figure out how to play it.
Slot machines, on the other hand, were terrible. If most people just buy the coins instead of playing the crappy games, just put those items or TMs somewhere else in the game where we can buy them for money instead. The Game Corner in general was a terrible idea, except for HGSS.
NO MORE FUNERAL CAKE UNTIL I CAN BE A GOOD GIRL do you wanna die or just come real close?
Voltorb flip was easy, but it took so damn long to get enough TM money even if all went pretty well. Gambling as a whole is BS and should be removed from this world, so I really don't need to see it have any importance in Pokemon. They can make a mini game corner for the people that like doing that crap, without any exclusive stuff in it.
