Can I then present the game as a modification to the tabletop simulator? Or are there other ways to display a board game via itch.io ? I've just never seen tabletop games being shown through this website.
People have made their TTRPGs available by providing the rulebooks and other necessary content through PDFs. You can look for some examples in the physical games section! https://itch.io/physical-games
If your game must be hosted off the website in order to be played, then I apologize but it cannot be submitted to this jam as we must be able to verify each entry
