Okay, here's the essential problem with Wizardry II: you can't create characters in it. Instead, you have to import your characters from Wizardry. Now this would be okay, maybe, if during the import the game auto-leveled you to something sensible, but it doesn't. Also, when you import your characters, it permanently removes you from the original game. You can't even go back and re-import them if they die. Man, these games are harsh.
Remember how in Wizardry I, I kept losing my party because the game auto-saves and death is permanent? Well, the same thing is true of Wizardry II. Now this was bad enough in Wizardry I, when I had to create characters from scratch and build them up to a high enough level to either a) rescue the bodies of my original party or b) replace my original party. But in Wizardry II, if I lose my party, I have to go back to Wizardry I, create new characters, build them up in Wizardry I, then import them to Wizardry II, and finally send them on the rescue expedition. I'm sorry, but I don't have that kind of time.
I might do it if there was anything different about Wizardry II, but the manual that came with The Ultimate Wizardry Archives confirms that the gameplay, classes, races, spells, commands--everything--is exactly the same. Even the names of the equipment shop, tavern, inn, and temple are the same, despite the fact I'm supposed to be in a different city. Wizardry II isn't a new game: it's a new dungeon in the same game.
I did try. As you may recall if you read that entry, only four of my characters survived the final battle in Wizardry. I imported them into Wizardry II along with two level 1 characters I created in Wizardry to take the places of the dead ones. I figured that I could keep them in the back of the party and just build up their experience using the other characters. This worked for a time, and I got them up to level 6 (my other four came in at level 12). Unfortunately, one of the dead/replacement characters was a mage--the only class that can cast the MALOR teleport spell--and on Level 1 of the Wizardry II dungeon, you need the MALOR spell to progress.
Wandering around on Level 1, I found a room in which the sorceress Gnilda (the creators' anagrams are showing again) spoke about the main quest. The City of Llylgamyn was once protected by the magical Staff of Llygamyn, which prevented any evil-doers from entering the city. Regrettably, the staff had a loophole: those born in Llygamyn were immune to its preventive effects. Someone evil named Davalpus staged a coup and slaughtered the royal family, and in the ensuing war the staff was lost to the depths of a dungeon and the city brought to rubble. My party's quest is to recover "symbols of Gnilda's favor" so that she'll give me the staff and I can restore peace and prosperity.
Unfortunately, Llygamyn is going to have to remain a smoking ruin, because shortly after receiving said quest, my entire party--even the veterans--was slaughtered by a group of "kobold kings." No way am I re-playing Wizardry just so I can have characters at a high enough level to start Wizardry II. The process of importing, creating new characters, starting up, and mapping Level 1 took close enough to six hours that I feel like I've kept within my rules.
Now isn't everything I'm saying also true of Wizardry III? Yes, Wizardry III also does not allow you to create characters; you must import them from the original Wizardry. But according to the manual, you're not really importing the original characters but rather their "descendants," and during the import it re-sets you to Level 1. You don't even get to keep your gold. Hence, since unlike II, III doesn't require high-level characters, I have no cause not to give it a try.
Since Wizardry II is the same game as Wizardry, I see no reason not to give it the same overall score: 37/100.
The manual that came with the Archives is a lot of fun, full of comical little drawings of your characters. I wish I could show it to you, but my scanner is broken. It also explains things a little better than the original manuals. Flipping through it, I have to say, Wizardry VI and VII look pretty cool. I'll get to them eventually.
Edit from 26 March 2014: Nearly four years after I first played this game, I returned to it and won it. The GIMLET score fell to 32 upon consideration of the game in its entirety. I recommend that you read my updated post for more information about the game.
