I think it all depends on how much fun the game is :)
I could imagine because of the unique game design it could build a strong core community around it.
But for casuals it could be difficult to have success as far can see :)
After I the video I become another question,
What ELO/ MMR + match-making system will be used?
There is a change to abuse ELO/ MMR games at times not many people play. If you earn more Coins for longer games, you can play yourself.
Because of the Return in EXP coins, it could be profitable because of the ranking.
The Match Making system is something I'm really interested in.
GM!
