Well, first of all a huge thanks for this generous offer! Don't mind the elderly here that fear anything new and apparantly forgot basic politeness. The only thing I give them is recently there has been an instance where a new person promised a lot, but ended up ghosting once the reality of the challenges sunk in.
Usually I am very inspired and come up with all kinds of ideas. But honestly, I can't think of any thing.
Well maybe one thing. My schtick is that I am a bit of a game designer (amateur) and I am convinced that the big5 (8ball, 9ball, 10ball, straight pool and 1p) are great games, but they all lack *something*. In my post history there's a post about the search for the perfect game, a game that has it all, but is really hard to design - obviously.
Your question however is not about game design, but about mechinal engeneering. Well, one avenue in the search for the ultimate new poolgame is attributes on the pool table that modify the table. Like gates that could be passed or little "rail" islands. Altogether this is nothing concrete, just an idea that floated my mind.
For
Elimin-8-ball it would be great if the pockets that are eliminated would automatically close.
All these are endavours that I honestly would not ask anyone to put a lot of time and energy into.
The digiball fills a void that we kind of knew would be a "very nice to have" and it's turning out fine. There's a company building topdown projectors that create (probably gimmicky) minigames for the party crowd. Imo with talented game designers they could make briljant games, but they probably aim for candycrush-pool games, if you get me.
So, a very long post to say: I don't know. But again, it's a genereus offer a d I hope someone has a really good idea.
