So far I've had a lot of people look at and download my Free version of the 16 bit school asset pack: https://ghostdatamedia.itch.io/free-school-assets-pack which is great but I don't know how well it works for RPG Maker XP, MV, or Ace because I use none of these. I use Clickteam Fusion for game design and making assets.
So for those that have the time to discuss their opinion on how well it works or doesn't work in RPG Maker please let me know!
