Legacy Collection perfectly preserves six classic Mega Man games without any extensive modifications. What changes it does bring are entirely optional and only serve to enhance the experience.
Perfectly preserves six classic Mega Man games; Challenges are a fun way to remix old stages/enemies; Quick save and load is there if (when) you really need it
Would have loved to see it span all 9 Mega Man games; Restarting challenges is a bit cumbersome
