There have been a few topics about this in the past. Here's one:

[quote name='Cao Cao']For the GBA, you can't go wrong with any of the Megaman Zero games. Megaman and Bass is another good one if you want the old-school pre-X style of Megaman gameplay. As for the Megaman Battle Network series of Action-RPGs, your best bets would be with BN2 or BN3.
BN1 has a generic storyline of "Oh noez! Dr. Wily is trying to take over the Earth/Net! Megaman.EXE must stop him!" and the games after BN3 had some pointless gimmicks. BN2 had a much improved storyline over BN1, and it was the last one before Capcom decided to do the Pokemon-style "Two versions, same game" thing. BN3 has two versions, but either of them are good, as BN3 also has a good storyline. Plus, as I stated before, it was after BN3 that Capcom started to add some pointless gimmicks (Dark souls in BN4, some strategy segments, etc.) that had a tendency to harm the game more than they helped.[/QUOTE]
[quote name='Cao Cao']Battle Network: Yeah, they all have a "played one, you played them all" feeling. But really, 2 or 3 would be the best routes to go as they had the stronger storylines in the series, without adding some half-baked gimmicks.
Zero: It's definitely a series of tough games. I remember some time back that there was this thread with a big debate over how the difficulty evolved for the series. There were three significant sides:
- The new features added made each sequel significantly easier than its predecessor. I think this was a position taken primarily by veterans of the series who played through each game as they came out.
- The punishing enemies and level designs more than compensated for any new features, making the series even tougher.
- The factors above complement eachother to balance the difficulty out in each installment, making them all nearly equally tough.
But I just can't find the topic that had this debate. During my search for it, I did find a few more topics related to Megaman:
