Gotta disagree. I loved Megaman Battle Network. I thought it was extremely fun for an RPG. I loved how you could jack in to tons of different stuff, and I thought it was fun to poke around at all the secrets in the game.
I don't like Starforce though. It really is an inferior version of Battle Network.
I have to admit though, I am totally gay for Megaman. Megaman and Mario are pretty much my favorite franchises ever, so my love of Battle Network might partially be biased by the fact that I loved how you could fight a lot of classical megaman bosses. Snake Man was very disappointing though.
