Dark Elf, Dragon, Dragon, Dragon, Dragon. What a party! You can simply spam the autoattack and cruise through the entire game. Truth be told, five liches is probably even more unbalanced later in the game.
Anyhow, MM8 was rather good, and indeed - the last good MM game. MM9 is merely "okay", and a dissappointment once you've played the older, much better games (among the finest RPGs overall, imho).
Regarding the spiders. How many times did those disgusting little creatures make me jump out of my chair because of a sudden *hiss* from below the screen? No idea, but enough to make me go on a crazy killing spree every time I saw one (i.e: "DIIIIEEEEEE SPAWN OF DARKNESS!!!").
