I highly recommend taking your time and enjoying Mega Man Legends 1, and then don’t necessarily let MML2 intimidate you, you don’t have to commit to it, just give it a try, skip tron bonne and jump right in to part two after letting part 1 rest for a bit. The first parts of the game, before you go to a different continent that isn’t covered in snow, is amazing, and worth experiencing just on it’s own.
Heck, you could even play it while you’re still in the middle of Mega Man Legends 1. It’s just a couple hours long, and it’s letting you know what’s ahead. It’s much too easy to just ignore MML2, because MML1 is already so perfect.
