The official Saturn Twin Sticks are one of the most sort after game controllers for the Saturn after the Astro City Arcade panel sticks. Basically with a pair of these arcade looking Twin Sticks, Virtual On becomes the arcade game! That's how good these sticks are. Pure arcade quality hardware for the home and best of all, they aren't that expensive. Other games that use them apart from Virtual On include Gun Griffon 1 and 2 and the 3 Gundam Side Story games. I'm sure there are other titles as well.
Below you can see the actual Twin Sticks in all their glory. They sure do make the plain dull Dreamcast Twin Sticks look very sad indeed. At least these mimic the arcade originals,
