They fix what the first 2 games did wrong, let you skip cutscenes, have a bunch of modifications and skills, one of the coolest weapons. The OST is better too. Cyber elves can be permanently used as well

My only complaint is that you have to have an A or S rank while defeating a boss to get its EX Skill which really sucks, but otherwise this game is just goated

My top 3 Mega Man games are 100% X, X4, and this game.
