This is a nice sized screen that can be used for more than just games. I use it instead of a tablet to watch movies and can give it to children to watch movies with a USB device attached to it with the movies on it so I can control which movies they can watch. They can also play games and there are so many games on this device it is mind blowing. For those who owned games consoles in the 80s and 90s there will be a lot of nostalgia but I had computers at that time so it takes me time to get used to the game controllers, and of course most of the games are quite hard and take time to master. There are way too many games to try them all in any sort of reasonable time period. Essentially you could try 10 different games every day every week every month for a decade and not play the same game twice. The list is so long I have chosen a dozen different games from the list and they seem to be quite similar so dont expect a huge wide variety of games, but if you have nothing to do it is worth the money just for the screen which can show movies or be connected to your phone or tablet or laptop to increase your available screen area. Reasonable price for what it is and I think if you buy other retro games with microSD cards with game on it you could probably play most of those games on this device as well, so great replacement for a lot of different games consoles.
