For sure. Easily half (likely more) of my unplayed games are Bundle games from a bundle I got primarily for something else. There’s a few gems I’m sure.
There are a few games I bought on sale to play later as well (I’ll get to you!) but the other glaring flaw I see is a selection bias. The people who use this service or similar services are going to be the heavier Steam users with collections in the hundreds.
So heavier users, with lots of bundle games and sales. I’d divide that total by 10 at least
I was 95% k+m until the Steam Deck (the 5% being my old Saitek Flightstick).
Since the Steam Deck I’m probably 90% controller.
I will say that k+m offers superior speed and precision, especially in FPSes, but the biggest improvement that I noticed was that I was getting a sore shoulder from repetitive strain sitting too much time in front of computers. Controllers are more ergonomic.
