That looks more like an image from the Hubble Telescope than a skill tree. From your descriptions, it looks like there are potentially hundreds of hours of gameplay in POE2.
From a value standpoint - that great and perhaps perilous, you can probably play this for hours, the peril of course is you might play this for hours - it looks like a potential time destroyer :) I'm somewhat glad I don't have a gaming PC or I'd be tempted to get this.
I think you can play it on console too, but I don't own one of those, so I don't know for sure. I only installed it on one of my computers so I am not tempted to play it all the time. I only get to partake of it in brief spurts!
