I know there have been numerous attempts to re-invent dice games, including dedicated coins, ETH contracts, ERC-20 tokens... IMO they are all pretty far from the holy grail of on-chain number games. Don't get me wrong, I know it's super-easy to criticize and point-out mistakes, but there is a good reason players aren't using them 24/7.
ICOs can be indeed tricky (good point) and actually I prefer building the product real product (or at least a solid preview) first then selling vapourware.
Anyway, these are just plans. I have some alternative projects to work on (and my family to be with), so it's not that I'll immediately jump into the next crunch :-)
with the good reputation you have, I'm sure it won't be difficult for you to market new products again...
I saw some gambling sites issue their own tokens, maybe you can imitate their way.
