Still—the game’s name and visuals don’t really have any cohesive GTA or Runescape elements that blend well together in any way, as far as I've seen it. It just doesn’t make sense to mix medieval classes, textures, and artwork with GTA Textures and Artwork in any way.
It just seems like its made to ride on the name GTA… I mean, even your link “gta6solana” was 100% intentionally chosen that way… You can’t tell me you did that without an ulterior motive.
