Don't miss this if you are a Sonic fan
This package has the major Sonic games- Sonic 1, Sonic 2, Sonic 3, Sonic & Knuckles, along with Robotnik's Mean Bean Machine (highly addictive), and some lesser-known titles by Sega but not for Genesis.
The package is a direct emulation, with all the old glitches and cheats.
The games themselves are mostly self-explanatory and take only minimal learning time, but this doesn't mean that the games are a write-off in terms of difficulty. However, they are nevertheless completely engaging. I'm able to spend hours and hours playing without noticing the time passed.
