Before the days of the internet, several fantastic games never got a chance to shine. One of these was Tomba!, which is easily one of the best platformers on the Playstation 1. Despite the poor sales at the time, the game currently sells for $60+ dollars on Ebay. However thanks to MonkeyPaw Games, you can now purchase it on the PS Store. It will cost you $9.99 and should work with your Vita after the Playstation Classic support update.
If you would like to know more, you can find a video of the gameplay below.
