It's not really something new, Most games already tend to have in-game tournaments/event's which they would be rewarded with from cash or in-game loot. There's even certain site's that you are able to bet and play as a team, but majority of these are fps games which only allow games as teams, As far as i can see these guys combined what was missing in all these platform's and even made it a whole complete system where player's can be rewarded. But i'm really curious about how much would the fee for withdrawal's be, what their terms would be, how there community would be treated overall etc.
My personal opinion on the game would be horrible though, just by seeing the trailer i can say i wont be playing these game. The game looks like a half baked combination of Doom & Dirty bomb. They could really improve on many aspect's. It really does look like a old game, slow movements on a futuristic battlefield is a huge bummer for me.
