Ok, I've only just started looking at workshop for this game, and let me say wow to some really incredible work... this post got long as I brainstormed so I made a TLDR; at the bottom.

Where is the love for FFIX? :o
Haha. I realize it might be easier to do with something like, an outfit like Nero's for example, with a closely contemporary model readily available... I'm not sure what model, if any would be available for Zidane from FFIX... or how that tail of his would work hehe :o but still... given what some people have achieved! For instance the Cloud and Squall attire's look great!

or one of Zidane himself : )
Though so far I prefer just the outfits for characters rather than replacing any characters : )
(although in these few cases, I might make an exception for some hours of play ; )

Another one I was surpised to see no results for was Kenshin Himura :o
The kimono of the Battousai would be cool indeed : )

And now that I think of it, Hiei from the dark tournament, that outfit would look rather befitting on Noctis! IS there a Hiei outfit? :o *goes to check*
^_^
At any rate enjoying what is here, so thank you awesome workshoppers!
*comes back* There's no Hiei yet! :O

Vergil? LoL! Ok so 2 turned into 4... xD
Someone with modding abilities far beyond my own, take these ideas, n Run wit' it...! :D
If anyone does Vergil, take note from the dmc4 models;... Nero's outfit befits Noctis much more believably, the shoulders and everything just kind of rests weird on the DMC4 Dante outfit port... though it is a fine port. I would be interested to see outfits for Noctis of DMC 3 Dante and Vergil... ! (Always preferred the aesthetic of both Dante & Vergil's faces and attire in DMC3 to 4...)

This is a long post man. +1 Stream of conciousness. And two turned into five requests, hahaha. Hopefully I don't sound entitled ^_^ :D But I just hope that some of them may maybe get made, because given the really awesome ones so far, I think these are great ideas! ^_^

TLDR; (note if you skipped here I said in general I'm not looking for models over outfits, but would be okay with it : ) )
Outfit for Noctis (And/Or Model) : Zidane, FFIX
" " : Kenshin Himura, Battousai, Rurouni Kenshin
" ": Hiei, Yu Yu Hakusho, Regular/Cloaked appearance, &/or black ripped tank top from Dark Tournament with bandaged right arm
Outfit for Noctis: Dante's attire from DMC 3
Outfit for Noctis (And/Or Model) : Vergil, DMC 3

: ) If they are not doable, they are not doable, but hey, now it has been put out there : )
