Super interesting article about how sales like Steam's can be bad for players and developers alike. The alternative pricing model like Minecraft sounds reasonable, as pre-order sales have shown over the years.
It's by Jason Rohrer.
I've certainly met some of them: people who have a backlog of 50 unplayed games in their Steam library. Maybe they'll never play them. But even if there are enough people doing this, it's not a good thing. It's just people being tricked into wasting money on stuff they don't want or need. Better that they spent that money on one full-price game that they really want rather than four 75%-off impulse buys to add to their backlog.
Yup, I'm of this mindset too. I don't buy many games in the Steam sales, I bought 2 games during the last winter sale. It's not a matter of already owning the games in those sales, but what I'll want to actually play than leave it to rust in my steam library.
