Apparently the Apple and PC handle experience very differently, making for different games. But I do love how MM2 has some basic and clear violations of logic--and that for the most part adds to the game.
Can't vouch for this, but I *can* confirm that the two versions I own - PC and Sega Genesis - play very differently. PC version has party formations with front row and back row characters, with the back row only able to attack with bows, and some spells not working if you're in the front row (and others only if you are). Only front row characters get struck though. Genesis has no rows and enemies just attack your characters in order, and the point of bows is pretty much lost.
Some monsters have their abilties switched around - dare I say juggled - too. It's funny the Juggler was named as a specific example as he's only annoying in the Genesis version, where he inflicts a bundle of status effects, and completely "are you freaking crazy" deadly in the PC version where a group of Jugglers starts the battle by all juggling all party members for serious damage, leaving you most likely dead before you got to do a damn thing.
M&M2 is odd, it's often fluky, the best fun is to be had in all the ways in which it can be deliciously broken, so your final conclusion that the game breaks all rules except for being interesting is dead on. I do have to wonder how many of the things you refer to in your review - things familiar to me and bringing out the nostalgic knowing smile at least twice a paragraph - are going to be comprehensible to someonw unfamiliar with the game, though. Then again, the audience for a review like this IS people like me, who even if they don't know the specific game do have a grasp of the tropes of RPGs of this era. So I may be worrying too much.
