Nah, I dont agree with you at all.Not all NES games hold up today obviously, but its still a joy to play a megaman game, or a castlevania game for example.
Honestly, it was with the 3rd gen that gaming actually started to get real good.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
