Peak mega man game, definitely the hardest of the classic games but immensely satisfying. Both characters, despite what a lot of people say, are really balanced and have their own sets of advantages and disadvantages. Plus has a collectable system which encourages you to play the game twice with both characters.

The weapons in particular are great and there's a lot of crazy stuff you can do with Ice Wall and Lightning Bolt in particular. Ice Wall allows you reach higher areas, and has a niche technique where you can jump off it and switch to another weapon for the height advantage in a boss. And lightning bolt lets you stay in place on the screen which has a great use in a lategame boss fight. The game's expanded shop system and it's different approach to the level select makes it feel really fresh and new in comparison to other Mega Man games.
