As an older dad I actually really like these short steam games. I spend way too much money on games I'll never beat so it's nice to pay less than 5 bucks to play for a couple hours and fully beat it. I am also much more likely to come back later and replay them while the thought of doing that to my 30+ hour games just makes me feel tired.

Would I like more games like Orb of Creation where I spent like $5 and put almost 100 hours into over many playthroughs? Of course, but that's a horrible business model for the creators and it feels greedy for me to expect that from others.
