Sweet, Cameron Browne is the tech lead. He's designed a whole bunch of abstract games (his boardgamegeek page[1] credits 71 games to him).
I looked at the language and db reference and it looks pretty robust for abstract games, as someone who's made a pathetic attempt at coming up with a generalized system to facilitate putting my game designs out there myself in my spare time.
Might see if I can port a couple of my designs over to Ludii at some point.
