The 8 steps to create a board game on Board Game Arena are:
1. Volunteer to join the developer team and choose a game to adapt.
2. Develop your game using the online Studio environment and resources provided.
3. Test your game extensively online with other players.
4. Submit your game for review by the BGA team and game publisher.
5. If approved, the game launches in a "silent launch" period with limited players.
6. Following bug fixes, the game enters a beta phase open to all players.
7. Once stable, the game is fully launched on BGA.
