Despite being one of the oldest platformers still a great time, and a game that tries to differentiate its levels more than you would think. A shame about repeated levels, but knowing Nintendo if they were to shorten it to 7 worlds, every Mario games after would have 7 worlds.

Mario's first outing is a pretty solid one. The physics are kinda eh and some of the castles kinda blow without a guide but it's still a fun time.

If you view the game more as an arcade title similar to other games at the time then a lot of the design choices make a lot of sense, imo. That being said, the modern 2D Mario series is definitely more accessible and refined.

Honestly still a fun replay.

Yeah, it's a classic, but you have no reason to go back to this when Mario 3 and Mario World both exist.
