About a year or two ago I played a least halfway through the first MMBN. I liked the setting and the battle system was cool overall, but I couldn't stand how long and especially convoluted the dungeons were. Random encounters get incredibly annoying when you're always dealing with some annoying puzzle that sends you all over the place. Even the network itself was a confusing mess of a maze, navigating it was a pain. So in the end I dropped it. But I heard the sequels improve on that. I also hear lots of opinions about which one is best. Some say 3, others say 3 has lots of backtracking. If I'm going to beat just one of them, which one should it be, knowing I don't want anymore headaches?
