Hi Overalll_
If your game is a commercial Steam title, you generally should not use Minecraft branding, logos, textures, characters, or imply any official partnership with Minecraft/Microsoft unless you have explicit permission or a licensing agreement. Minecraft's guidelines also prohibit suggesting endorsement or collaboration when none exists.
Steps you can take:
- Create original vehicles, artwork, and decals that do not use Minecraft IP or other copyrighted/trademarked brands.
- Avoid using names, logos, fonts, or assets that could make players think your game is officially connected to Minecraft.
- If you want an official Minecraft-themed bundle or collaboration, contact Microsoft's licensing/business channels to inquire about partnership opportunities before development progresses.
- Consider consulting an intellectual property attorney before release, especially if you plan to use real-world brands, decals, or licensed content.
This is a public forum, so no one here can grant permission or provide legal approval on behalf of Microsoft.
