Yeah, it ain't bad, I think if I was a new user with no video games or few games and I would get a chance to grab it for free I would play it so potentially a new user join their platform. Honestly, I'm impressed there are 12k users daily on Steam which makes me think there are way more on their platform and I don't know if the game has crossplay.
Yeah unless they have tons of games and they find a good deal for a second-hand console, I was checking a few days ago prices for the PS4, handhelds,older Xbox consoles. But there is always a risk buying one in bad shape...
A PS4 is around 100$/Euro which isn't bad usually people sell it with a controller and a game or two. On the other hand, ps vita handhelds are double the price, Xbox one 100$/Euro, Xbox 360 50$/Euro
