Sexcoin is worthless as is any "Game" coin. Having done work for companies in both industries, I can say with a certainty that they have zero interest in those sorts of 3rd party things.
Been following DigiByte and GAME, besides others who did not made very well. DGB had a hard time and merely "pumps" on occasion, no track so far at their target audience. Unless we crypto people are the target

Dice of course has a meaning, at least if you can do it better than Satoshidice did. Well they had been a tremendous success but the brand name vanished, they had to block out US customers due to some law issues *besides* not having servers/company located inside the states but abroad, Dublin.
Game company interests would be awoken if a token remains as the only method left to dodge legal issues, and in a state like that any serious game development bussiness faces trouble.
