Santorini (DIY)
1985 (2007 edition rules) / Strategy board game / 2-3 players
***I'd taken this for a kids' game when seeing the inappropriate cutesy box art of the modern editions, but its minimalist indie precursor is much more appealing, not least for inviting intellectual property theft using whatever unobtrusive tiles and other bits you have lying around.
I put unloved, unsellable Flanx tiles to use (two sides of two colours for the base plus three levels), with Atmosfear figures for fun. I didn't like the game all that much, but at least I didn't have to spend anything to find that out. Next project.
