Come on, Body Blows is great when you have never seen any other beat em up game, just like Fifa soccer,ProEvo are great if you dont know Sensible soccer or GOAL!
Which brings me to my contribution to overrated games in history:
Sensible Soccer! Yes! It is a simple fun game, but it has little variety, you cant do much with the ball. Its a game for kids, I still play it with my 6 year old nephew on my Amiga 600, he loves it. But when he is older, we will play Goal!, the best football simulation ever.
