That's an interesting project for sure, thanks for sharing the links. It's great to see that there's so much crowd-support for innovation like this, and I wish them the best of luck. eSports was never my cup of tea, but I might know some people who would be interested in the project.

I didn't look too deeply into the mechanics, so I may be speaking out of turn, but I think the elegance of Steem lies in not having to buy in to "play." Without those mechanics, you have the same challenges as a tipping platform; not everyone wants to buy in and risk/spend their real money. Not that it isn't a great solution for the competitive scene, but that's its limited in scale because of that hesitance.

Again, this is from a cursory review, so I may be way off base. :)
