As a lad, I remember the Sega Genesis being the pinnacle of home computer entertainment systems. My television was rarely used for actually watching TV and every main present at Christmas was cartridge-shaped. It shows how far we've come (or how old I am) that I can now play Genesis/Mega Drive games on my phone for just a few bucks. Of course, the experience isn't quite the same as the old days, and the iPhone touchscreen isn't always conducive to intuitive console-style gameplay. However, if you're looking for a cheap thrill that will take you back to the glory days of the early Nineties then get these Sega classics on your iPhone now. Load up iTunes and click the links to the App Store pages.
