Mega Man Battle Network Legacy Collection Vol. 2

Comprising Battle Network 4, 5, and 6—along with their various version splits like Red Sun/Blue Moon, Team Colonel/Team ProtoMan, and Cybeast Gregar/Falzar—this volume offers not only a huge amount of gameplay but also a comprehensive look at how the series matured, both mechanically and narratively.

Personally speaking I haven't played much of it, but Battle Network 6 PVP is REALLY fun.

However, the story—which centers around the kidnapping of Lan’s father and MegaMan’s own corruption—adds an emotional depth not often seen in earlier entries.

For fans of the original releases on the Game Boy Advance or curious newcomers intrigued by its genre fusion of real-time grid combat, deck-building, and story-driven progression, this collection serves as both a time capsule and a polished reintroduction.

BN4 while rough still has some qualities I like about it such as a very visually appealing net, double souls being op, a great soundtrack, and couple of laughs from its old goofy translation errors.
