I think a big thing was that I was expecting it to be free throughout its development, because that's what they kept saying, then when they had the release announcement a week before it came out, all of a sudden it was 30 bucks.
Now, it's possible that that was their idea all along and I missed it, but all I kept seeing was "Gwent Game will be free!" The beta was free, all of it was free, then bam, 30 bucks.
I'm not saying the game isn't worth it, but most of us have a budget, and 30 bucks is a not a trivial amount for most people, and my gaming money for the month was already assigned to RDR2. It also didn't help they released during the busy season.
So... yeah. Sorry guys. Love your games, but this may have to wait until like April next year or so.
