On this small handheld game, it may be small but there are so many games on here. I have had this game for almost a month and I still haven't been able to go through all of them and play them. However, I can say that I have been playing a lot of my old favorite games. The games on here are just like the ones I used to play when I was younger. All of the graphics and moves are all of the same, nothing has seemed to changed, except for it's on a handheld console. This game is fully rechargeable and rightfully should because of how much I've played on this. What is really nice about this games is that whatever I am playing on this small screen, I can hook it up to my television and play it on there. There is no delay or anything like that. As soon as I move, the game moves when it's shown on my television. I have been able to show my kids all of my old favorite games and have been able to show them and allow them to play them. This game has been so much fun and the battery lasts for quite some time before I have to plug this in to charge.Cool, little retro game. The Mario and ninja gaiden, and TMNT, and awesome stuffThis is INCREDIBLY COOL!!! I’m in love with it! Greatest product in foreverGame Nintendo have great games on it but you cannot enjoy it because it doesn't work long before it starts to mess up not a such a great product to buy then enjoy it as much it should be have a corny warranty on it I wonder how to use itDay 2 of playing a game for less than 10 minutes and the graphics is shot. When i turn it on you can hear the games but cant see them. very cheap qualityDefinitely a great buy! For someone in their 30s, I was very impressed with the bargin buy this was! Of course it does not compare to all be hi graphics games they have out right now, (our kids will never know our struggle) LOL But the fact that it has ALL of the games that I had to buy individually on my original game boy blows my mind!So far I have played Mario Brothers, Dr. Mario, Tetris, Pac-Man, I can’t believe it has all the games are used to play! Great game for kids in the car or to keep busy! We bought a bunch of them for Older kids for the toys for tots at Christmas time too, hope they like it as much as we do! Great buy!If it was 1990 I’d die for this thing. But Mario is my favorite game and it’s “run and jump” button is off a little. Not a huge deal but if you’re used to the timing of a normal NES then you won’t want to play on this thing. There definitely are some playable games, such as Tetris and Pac-Man and a bunch of Asian versions of Mario. I haven’t hooked it up to a tv yet so I’m not sure how well the tv controller works. Definitely worth $15. Probably wouldn’t pay over $25For the price this thing is pretty cool. I will say it's frustrating when you select certain games and complete different games show up that probably were never even released in the United States (Paperboy=Frogboy which is a knockoff version of Super Mario Bros 1).
