I think this is a good rundown of the game

It is live service, and I’ve gone into it being fully aware of the founders pack way of doing things, but if you stick to one character fairly early on you’ll be levelling them and racking in points just fine.
Edit: it runs great on deck too apparently, and looks like cross everything, so I’m tempted to get a founders pack on steam too.
