But imagine the mods. You can't deny the prospect of a mod-friendly KH being interesting at the very least. IF it's used creatively, as opposed to 'my original character, Xeebob' or waifu mods.
Oh, definitely. The potential is boundless, especially to fill whatever voids will be left in KH3. NPC mods if they only have a small number, a weather system or day/night cycle, up the particle effects on spells and flashy attacks, and framerate mods.
(Though I'm the type that'd totally go for cosmetic changes like every make character made shirtless, or replace Keyblades with brooms...because I'm just that trashyclassy~)
