We started playing this on PC. So far it's me, Yurian, danjiro, recoil and Robomoo using his brother's account. Saf also has the game but hasn't played with us yet.
It's a good game and I recommend it to everyone. I'll make a longer post in the Games forum soon, I have a lot of things to say about it. I don't like it as much as Siege or PS2, but it's still a good game and with enough differences from everything else we are currently playing to add it to the rotation. I think the best thing it has to offer is the character variety, which is even more wild than Siege's. I can see myself exploring the various heroes for months. Aesthetics are also great, and a nice change from PS2's monotony in that regard and Siege's ultra-realism.
Need to play Paragon too so I can compare it with something that's closer to it, mechanically. Team Fortress 2 was also mentioned as having similarities, and I was intrigued by the 12v12 mode Robo said it had, and since both these games are free I'd like to give them a try at some point with whoever's interested.
I posted about a good Overwatch deal here: http://culture.vg/forum/topic?p=28597#p28597
