Goign to be streaming some Breakaway tonight. It's the first game made by Amazon in partnership with Twitch so has a fair amount of integration with Twitch. playbreakaway.com is the site. It's interesting that while playing you can see how many people are watching (it adds up all the people watching each player, also shows who is streaming) Also your in-game names are your twitch names. The game itself is a combo of moba and rocket league. Big plus is that it's super easy to follow what's goign on, even to a neophyte.
Basics are there are three ways to win a round, and first to win 3 rounds wins. Rounds are 4 minutes each. First way is to get the relic in the opponents goal (relic is just a ball really). Second way is to have everyone on the other team dead at the same time. Each time you kill someone they take x seconds to respawn then their respawn timer increases on their next death. Eventually you can use attrition to get them dead. The third and final way to win is to have the ball on the opponent's half when the timer hits zero. So basically as the round timer winds down, you get into a vicious back and forth of just trying to keep the ball over the line on the middle. It's quite tense and kinda exhilerating.
The other thing that is novel about the game is that each character has a buildable they can place one of each round. These stay around until destroyed, so in a long game that ends 3-2 you could potentially have 5 of those per player out, though that's pretty unrealistic since people will destroy them.
At any rate, I'll be streaming even though my framerate is a bit bad and my skill at the game even worse ;) It's a true alpha though so bugs are likely to abound.
