I have no idea what people like about Steam...
In short - easy way to get a refund, if you have any problem with the game or dislike it - as long as you don't have more than 2 hours on record for this game and your purchase didn't happen more than 2 weeks ago. Refund is automatic in this case, even one might have to wait a couple of hours until the money is back in your steam wallet. To me this is a huge benefit - because gaming companies are rarely that generous.
