Let's get one thing straight to start off with: these are not arcade games - as in, they do not have the type of smooth graphics seen in games machines in arcades, or reproduced in the Jakks TV Plug-in game-sticks. They are actually the 8-bit versions as seen on the Commodore C64 and Sinclair Spectrum. Having said that, it's still fantastic value for money, and brought back many happy memories of my C64. It's missing a few of my favourites, though, such as Wizball, Barbarian and Thrust. It would have been nice to see Elite included as well - I'll have to check the C64 emulator for these.
The controllers themselves are very cheap construction, and I'm not sure how long they'll last, but it'll be great fun as long as they do!
