Is Fishing Planet still worth playing?

Hey, I played FP regularly a couple of years ago until I was lvl 46 and stuck at the sturgeon/ salmon grind. Wasn’t so much fun anymore. I wanted to give it another shot and saw that they now changed the fast forwarding at night. I also saw that there‘s a lot of cash laying around in my steam account and was wondering if I could get to level 83 by buying the japan pack and if so how many in game hours it would roughly take? I don’t have the time to grind computer games for multiple hours every day anymore and just want to enjoy digital fishing :)
