My biggest downfall to the AtGames SEGA Genesis Classic Game Console is that the controllers. Not only do you have to be within line of site to read your controls, but you also have to have 2 AAA batteries that are not included for each controller. However, it really isn't that big of a deal, as most people sit in front of the console when playing anyway. Not to mention, most gaming items rarely come with batteries, so most gamers will be used to that feature anyway. I also love the ability to use up to 2 classic SEGA controllers in the system. Plus if you use classic wired controllers the issue with the wireless controllers is invalid.
Another positive to the AtGames SEGA Genesis Classic Game Console is the price. It is very affordable compared to the prices to today's generation consoles. However, it is important to remember this console is not made by SEGA.
