I don't think the problem is the many projects but a few critical choices made about this specific one.
Poker is fun, but cannot be played without a token that is perceived to have value (otherwise it's like playing with beans like children)
Wildwestpoker chips are backed by btc, which makes that game more interesting. It seems all the players still active have migrated there.
Tilt tokens sadly are considered valueless and that's entirely because of the system chosen.
Apparently it is very important to the dev to promote evolution or a platform like it, as a result he wants to make tilt dependent on that.
But players (me included) find that platform pointless until now and way too complex to use just for tilt. Meanwhile, there is nothing there to anchor a value on any of the tokens offered, so everyone is reluctant to make any trade.
The fact that the trades have to be made with derivatives makes it even worse, as does the fact that every deposti/withdrawal has to be manually approved by the dev. It's simply not a good system for the purpose.
Tilt could easily have been successful as a simple ethereum token. Not even a standalone blockchain. But it seems we'll never know
