I've been doing large scale distributed systems for a decade, and I still feel like I'm learning especially as I retool for games.
The way that I'm trying to make this simple is by inventing a new platform for "serverless game hosting" using my programming language (Adama : http://www.adama-lang.org/ ).
My focus on board game is the ultimate in server's role on authority since board games are more transactional between players and staggered (I play this card, that card enables another play to react, that reaction enables another play to augment, etc).
I'm looking into what it could mean to escape the board-game pit, and one thing that I'm thinking about is latency. The question that I'm looking at is whether or not I can have a programming model be differentiated such that the client prediction code can be generated.
A trivial way to exploit my language is to bring edge computing into the mix such that the edge compute runs a copy of the entire game, and then ships deltas quickly which will be overwritten from the authoritative server. This will work on updates to existing data (i.e. moving position), but it will fail at creating new items unless I move unique id generate to clients (which, is less than happy for me).
