FFVII Lost Wing CAN be completed...however, shit gets absurdly hard near the end of the game because I didn't really know what I was doing when I made the mod. You can get to the Huge Materia quests with a level 40 party, complete the Huge Materia quests with like a level 50 party, you'll need to be like level 60 and really know how to play the game to defeat Diamond WEAPON, and you'll need to be level 90 at least to defeat the Optional Turks Battle in Midgar and be really quite excellent at playing the game. I am at Proud Clod...and I haven't tried to defeat him with a good amount of effort yet. But when I did just walk into the battle with a generally equipped party he wrecked me pretty hard.
If you use a trainer or gameshark codes (depending on whether you're playing psx or PC) you can even the scales a bit by giving yourself all the materia and equipment. If you give your team a bunch of sources you can make it through. But generally speaking, if you're a casual player, you will be able to make it up to and complete the Whirlwind Maze and then you're gonna start shouting loudly about how much you hate me.
EDIT: Really, I just made the mod to have a new kernel (magics, weapons, armor, materia) and scene (enemy difficulty) to play the game with. I figured that anyone that was playing the game 15 years later was using all sorts of mods and knew all about trainers and codes and already had their own preferred way of playing the game. I just provided some new spells and equipment and made the enemies a bit more fun to fight. If you try to play LostWing without "cheating" in any shape, way, or form you better be damn confident in your FFVII skills, because I hold my own in high regard and I really don't know if I could beat my own mod without a few helpful little things (like having Aeris in my party for certain battles to use her Peerless Limit Breaks - which in vanilla 7 were super overpowered, but in Lost Wing are sometimes necessary late 2nd disc). And I always just give myself enough gil to make any purchases I need (3 of every materia, and at least 1 of every piece of equipment). Good luck, I'd say its worth it if you take everything I've said into consideration.
