Dealspwn: "As much as we love and respect developers of all sizes, we don't write for their benefit. We write for you, gamers, in an effort to inform you about games and just as importantly to save you money. As such, I can't help but feel that I should be encouraging you to partake in this practice. If you can complete a game and then get your money back, with no real effort and technically not abusing a system that has been established with no qualification as to why you should get a refund in the first place, I'm not sure how unethical it really is. In gaming terms, it's an exploit, not a hack.
After all, you don't have to get your money back if you feel the game deserves it, and more to the point Steam literally says that you can claim a refund "for any reason." Any reason. As such, "because I can" seems to be... fair enough?
Except, of course, that it isn't. Though I'm conflicted and the devil on my shoulder is telling me to encourage you to game the system, my conscience is screaming at me."
