Electronic Arts‘ 1991 release, Road Rash, is a fantastic motorbike racing game where the riders can actually punch each other as they are zooming down the roads.
This is obviously a very dirty trick to either knock other riders off their mount, or to gain some other kind of advantage, but it is allowed in the context of this game and it is hilarious!
Road Rash uses 2D graphics very effectively to create a convincing and speedy road-movement effect, and is adequately forgiving on the realism front too. This game has been designed with fun in mind – not realism – and it certainly delivers fun in large doses.
Road Rash is still a wonderful game to play now, only bettered – maybe – by Road Rash II and Road Rash 3.
