Sega Chief,
I've restarted the game under what I think is the most recent update. It's going very well so far and I'm attempting it a little differently than the first time I played, I'm grinding a tiny bit rather than rushing from place to place so it's been fairly smooth, albeit a little more time consuming.
Couple bugs I've found:
- Some NPCs seem to be missing dialogue or have it displayed improperly. For instance, in the building with the big spiral staircase in Kalm, the NPC there doesn't say anything. No dialogue window comes up and she'll turn towards the PC as if she was speaking normally. I have also had instances where dialogue choices haven't displayed properly, usually in the form of spilling over to the next line. The only one I can recall off-hand was the fellow in the house who tells you about the keystone, the issue occurred when I tried to give him mytheril.
- The battle square doesn't appear to work at all. When I spoke to Dio I was able to go through his challenge no problem, but if I speak to a receptionist and attempt to fight, I'm instead sent to the same battlefield found around Midgar, fighting a sweeper and one of those red motorcycle guys who are encountered around there. I've tried the battle square four different times with four different characters and the same issue persists.
Other than that it's been pretty seamless, haven't had any crashes that I can recall, and nothing else seems to have gone wrong.
One last thing too: I personally don't think the materia system ought to be changed too much, if only to avoid overly messing with the spirit of the original game. I agree that it's not a perfect system and may potentially involve some grinding, but I like the fact that it gives the option of grinding if the player considers it necessary. I feel that altering it too much could also result in a lack of flexibility, which seems to go against how you've designed this mod in the first place.
I do think that redesigning and shuffling around abilities isn't a bad move though, like tossing osmose in with Heal and remove with Destruct. Exit seems awful lonely though!
edit: whoops, totally missed the suggestion of using the two materia systems based on what difficulty you play, seems like the best compromise.
