Finally finished the game. That back to back series of dungeons at the end was tedious, as was the final "boss". Though I guess the grand finale was never a strong point in M&M, and this one is still better than the atrocious Square Lake Cavern. The slides at the end were a nice touch, but it seems as if only 3 quests use them (Haart, Lost Lambs and Owen's Ashes). They also bugged out, so I got both slides for Haart one after the other.
Speaking of quests I never found one of the books, didn't find the Shard of Light, and never figured out the deal with Montbard's daughter (or even saw any clue as to where to pursue this quest - it says something about a city in the Unicorn Empire, which I'm pretty sure is nowhere near the Peninsula....). I think all the other quests I missed were ones related to promotions for classes I didn't have, but some of these can be very irritating - especially one in the ancient crypt, since I found all the notes, had the disc, yet the ghost wouldn't take it and there was nowhere I could use it.
The game is really not what I expected, but I think I enjoyed it overall.
