Gonna be a long post...
So I finished the game today (finally), and I must simply say... bravo. *slow clap*
First off, the current issues:
==================
http://imgur.com/a/EsxJ5The adjectives used to describe the key, after the first one, are capitalized. Not sure if this is intentional or not, but they shouldn't be.
Is the bottom message in the controls dialogue box for the Steam FF7 removable?
You can only buy 6 stalls. The fenced area comes free of cost. The message needs to be revised to state that the stalls specifically cost 10k gil each while the fenced area can hold 4 for free.
I didn't take a screenshot of this, but only the Cloud model is corrupted in the chocobo mini-game. Cid is fine. Didn't check Tifa's model (lazy...).
Even after the date scene, there was still an action that affected Tifa's affection. If you could double check this.
At the City of the Ancients, when Bugen goes to put the key in, his signature phrase, "Ho, ho, ho", has every iteration of the word capitalized...
The two bottom menu boxes in battle has a 1-2 pixel gap.
Just noting this, but the item menu has 24 extra slots, and the key item menu has 16 extra slots. This is after considering being able to hold/contain every single entry in both menus. Don't see the need for the extra slots (manual sorting should be removed from the game...). I understand the space for materia since you can gain them indefinitely.
When trying to discard materia, you cannot quick nav with L1/R1 like all other menus. This is a pain because the list can be very lengthy.
Cait Sith limit break reel sound persist even after you cancel out of it.
Not sure if you can do this, but some materia can use descriptions as they are not exactly intuitive (i.e. Swap, Aqualung). A brand new player may ask what is being swapped, and they may confuse the enemy skill version of Aqualung vs. the actual materia.
When party splits up in the Northern Crater, there's no warning that the current party member's equipment was removed. There should be a warning dialogue so players can know that it happened.
On map las2_4, when you grab the yellow materia at the top, it says obtained 'Multistrike' instead of 'Double Magic'.
Mentioned this before as well, but the interaction between the newer models and certain objects are weird/funky at times.
==================
Now for what I think can/could be improved in future revisions:
~~~~~~~~~~~~~~~~~~
Mini-games can and should be more enjoyable. Not saying you should make it significantly easier, but the margin of error should be greater than what it currently is. So say for the marching mini-game, 45-50 first prize, 40-45 second, 35-40 third. This is considering how fast you can gain/lose points. Top prizes shouldn't require a top 1% performance to be obtained. I had some really hard tests back in school, but regardless of how hard it was, 90%+ was still considered in the 'A' range.
Models can be more refined much further. Lots of clipping and lots of silly, out of context details like Cloud laying on his bed with his gigantic Buster Sword. Some models also act really funky at times. Obviously this belongs in Kal's thread, but you can relay the message.
Not sure how this can be worked around, but Reeve's accent was played upon heavily. Without voice acting, his dialogue was a bit difficult to understand immediately at times. It required several rereads to become comprehensible (for me anyway).
I think you talked about this before, but perhaps one day you'd consider adding in the redone backgrounds into Reunion as well. It'll be a nice addition to everything else that has been touched up.
Currently, gil almost has no value. Resting at inns should cost a percentage of your total. I was thinking at least 50% of your total. This also adds value to the villa you can buy. You should also increase the price for the villa to something much higher. You should also remove a lot of the instances where the party gets a free restore to their HP/MP. But all this should be under the Weapon mod I suppose.
~~~~~~~~~~~~~~~~~~
Reunion has been a spectacular and warming experience for me. I already told you this, but Reunion is no longer just a mod, it should be required if someone is a true fan of FF7. Therefore, Reunion should be treated like so. You've pretty much touched every aspect of the game, so I'm not sure why you'd want to separate things from Reunion. Everything is and will be under the Reunion umbrella anyway.
Like I mentioned earlier, I'll probably return when Reunion has been even further refined, but I'm done with FF7 for now. I don't really want to burn myself out by playing the game too extensively.
