I'm sure, like many of the reviewers here, my first introduction to this game was on a TV screen with the Nintendo Entertainment System. It is as much fun now as it was then. To those experiencing this game for the first time, (and I know this may make me sound old) you had to be there. At the time, this was the best there was. That may not sound like much now, but you will be saying that yourself in 10 to 15 years about your favorite game that is in retro like this one. While this is not as fun as the "original" Super Mario Brothers, this is still a good play.A couple reviewers have stated this is a "hard" game. Um, the game is not supposed to be easy. It is supposed to challenge you. Deal with it. For me, half the fun is working to beat it. I've had the GBA version of the game for all of 48 hours now, am currently on World 2, and have lost many lives, but am having the time of my life. Yes, some of it is the nostalgia factor, but more of it is the fact that I never actually beat the game when I was younger. So the game shall be beat and the game will like it.As far as I remember, this is the same as the NES with maybe slight revisions to the background. LOL I can't check it out because my NES doesn't work anymore. :-( But if you are into straight-forward gaming, or just want a good old-school game, pick this up and enjoy.
