Great compilation, and a great price for it, but for anyone who may not know, it bears mentioning: this version of Alpha 3 has no "World Tour" mode, as it is based on the Japanese arcade release of SFA3 Upper, which contained the extra characters from the home console ports, but not the cool single-player modes, such as World Tour. Nor does it contain any of the extra characters added to the GBA and PSP releases.
Purists also complain that it doesn't run in the arcade's original resolution of 240p; it runs in 480i, or 480p via component. Personally, I still think it's a terrific package, considering everything that's on that disc, just be warned that the most diehard of fans don't consider it to be a "definitive" release.
It also includes Pocket Fighter!
