It's surprisingly fast. I got all the needed tokens in little over a week playing prett casually, no grinding. There are some cosmetic furniture I'm missing still but overall you get all the good stuff fast doing a few treasure hunts and challenges a day.
It's a shame it bombed buy I don't think we would have gotten GR3 for a long while anyway. I think Toyama and gang would have moved on to new stuff.
Oh boy a year and half!
Less than 5 I'd say. But there is a cooldown between treasure hunts for example.
Hard to say how long it will take exactly, but you can reach 6000 tokens after little more than a week with just an hour of play each day.
I'd argue it got overshadowed by Yakuza 0 which came out mere days after GR2.
You just shift from one area to another (or literally jump off and fall down to an area beneath you). There isn't any loading or anything.
