advancedhero: Wizardry 1 feels extremely deliberate and polished.
Having looked at the decompilation, Wizardry 1, at least in its original Apple 2 version, is an unpolished mess. For example, many HAMAN and MAHAMAN effects can't happen (and the game randomly chooses 1 of 3 effects, though it appears intended to have more possibilities, including some that are coded but can't happen), and there's a tiny chance of the character's spellbook being scrambled (the game generates a random number less than the character's (new) level, and only if it's exactly 5 does this happen).
Not to mention there's the Afraid status, which is only partially implemented, but which is accessible via the identify glitch. It has really strange behavior:
* (I don't remember if the character can act while under this status.)
* At the end of battle, the status is cured.
* DIALKO doesn't cure it, but MADI does.
* On returning to town, the Afraid character will be removed from the party. You can retrieve the character, or you can go to the temple to pay for the cure.
* The cost of curing the Afraid status is rather high (though it's *possible* there might be a way to manipulate it). Looking at the code, it appears the game takes an uninitialized variable and multiplies it by the character's level to determine the cost. (The particular subroutine only checks for the status ailments that can normally happen in town.)
Then there's also the strange way level drains are handled; your level drops immediately, but your XP doesn't drop until you win the battle or run away. This, of course, means that there's an exploit; if you teleport away (LOKTOFEIT or MALOR) or your party wipes (be ware that this can cause the permanent loss of the character or of items), you can dodge the XP cost and easily gain the level back, complete with the usual level up bonuses.
I could also mention dungeon levels 5-8, which seem rather pointless. (The Game Boy Color version removed those floors entirely and replaced them with a post-game bonus dungeon that requires beating the final boss to gain access.)
