This is....a really nice collection, hearing MegaMan.exe in the main menu is really charming (and he says special dialogs during certains days too) all the games are faithful to their original counterparts with some bugs fixes and the downloadable cards that were only available in Japan. Sadly i must say the collection doesn't have many QOL features which is a shame, also although there ARE online features the rooms are mostly empty in all three games, so you will likely need to find some discord server to play with others.

As for each game in the collection this is my review for each one.

MMBN1: Easily the most poorly aged BN, navigating through the internet and dungeons is an absolute nightmare, the story is barebones and the battle system although unique for its time of release is in it's most basic, barebone form. 5/10

MMBN2: Greatly improved upon the base of BN1, making a good deck is far easier and the form system really spice things up, the story also has better pacing at least until you reach the FreezeMan Scenario which kinda ruined the game for me. 7/10

MMBN3: Easily the best of Vol 1, the story is a bit better although nothing too spectacular, there's new forms and getting them is far easier, the Navi Customizer although annoying to use at times really adds more depth to the game, making every MegaMan feel at slightly more different. 8/10

If you want to try this collection, my only suggestion is to look for the mods at the Rockman EXE Zone forum and check the guides section of steam (is easier with Big Picture Overlay) since there's a lot of maps available, codes for special chips and location of viruses and what not.

best series in megaman if you like tactical games
