It's weird because normally having a monopoly is really bad but all the competition pales in comparison to Steam and they actually provide a good platform. Maybe after Gaben dies Steam will go to shit but for now they're not just the best but also doing way more than just being a place to buy games.
I'm expecting that to be the case, so I hedge my bets by also buying from GOG and praying for Gabe to have a long life.
