Ninja Gaiden

One of the best games I've ever played.Yes it's tough and it forces to think a lot more than the fighting games like GOW.The key to this game is to use the dash button, it allow you to avoid ennemies and their hits.Charging up combos is also very important
 
I do like it, I like the fact its so hard. Too many games are completable these days.

I remember back in the snes i couldnt finish half the games i started - and if i did it was cause for a room run around
 
The first one for the PS3 wasn't too bad but Ninja Gaiden Sigma 2 is possibly the hardest game I've ever played.
