When it comes to SEGA and their 16-bit library, game re-releases tend to fall into one of three categories. First, there are the games that are always included:Â Sonic, Golden Axe, Altered Beast, and the like. Then, you've got games that are often included, but not always. Phantasy Star 2, Ecco the Dolphin, and Shinobi 3 are examples of this group. Finally, there are games that SEGA only seems to include if they're being very thorough.
