May I suggest the option to convert coins into a store discount?
The last game I was interested in was “Heroes of Hammerwatch”, more than a year ago.
The only game I bought in 2019 was “Seeds of Resilience”, because I had more coins than I could possibly need and a friend had the game wishlisted,
Besides that I just sit on my 43k coins and get disappointed bi-weekly.
I’d be happy with a 10k coins per dollar discount ratio. Considering the games we got I’d probably even take 1/10 of that.
