Right now I'm playing through the Megaman Anniversary collection on Gamecube, it comes with 8 Megaman titles in one (and 2 bonus titles), so a lot of content here.
I've reached Megaman 7, and jesus christ, it is quite honestly the most boring Megaman title by far. Everything is insanely slow paced. Megaman's sprite is way too huge. I've seen a lot of hate for Megaman 8, despite the atrocious voice acting I loved Megaman 8, it was slow but it had some of the most lovable environments and bosses, Megaman 7 really lacks, other than Shade Man's level, most levels are insanely boring and short. Can't wait to be finished with this title.
