you can't get more classic than this game
Most main side-scrolling/adventure mario games get between a 9 and a 10. While other games like Zelda and Metroid may get better reveiws alot of the time, you still can never compare them to mario. Mario not only has side scrolling and adventure games like Zelda and Metroid, but has rpg, racing sports and party games as well. and this game started it ALL.
Super Mario Bros. is a classic and an extremly fun game for anyone who doesnt cry when a game has bad graphics. There are 8 worlds with 4 levels in each. 32 levels was an awful lot when you think about the technology 2 decades ago. I've heard a few people complain about the graphics, even though twenty years ago they were wowed by how reallistic mario looked compared to other games. I dont think this game is all THAT great anymore, where the boss fights are over in seconds and the variety of levels and differences in worlds is something thats come to be expected, but what counts is the memories it brings, sitting in my living room when i was 7 dying to figure out how to get past the maze of level 7-4
If you didn't have this game before, you should get it so you can get a feel of what video game history really was.
and if you did have it, it will really make you miss the glory days of nintendo, and video games all together, back when any good game was special, and no teenager was afraid to like E games.
