Donkey Kong looks really old-fashioned, but its gameplay is still fun nowadays! Nintendo decided to put out their classic games on GBA cartridges and sold them for a lower price than their new GBA games (15 Euro per cartridge, as far as I remember). Nintendo did not change anything in the game to keep it clearly classic. The control scheme is easy but it becomes quite challenging avoiding all these barrels, car jacks and fire. The gameplay is actually realistic because you will die if you drop down from high platforms. Donkey Kong is a pure "pick up and play" game which you can play without learning difficult control schemes. I think it was worth the 15 Euros, even though it looks old, it's a timeless classic!
