Hold on, wait a minute. I've been trying really hard to not call out or respond to specific users in this thread, but this one deserves a response for sure. Like you, I've spent hundreds of dollars on the PlayStation Store. There's been some games I really like and love, and some games I didn't like very much in the past. It just so happens this game is the first time I disliked a purchase enough to look into the refund policy Sony offers, and thought I'd share the experience and advocate for a better system in place than what presently exists.
I'm glad that you have the time to conduct research, field tests, interviews, supporting arguments and all of that. I'm a grown man with a job, a family, and more obligations. If you are, too, then I suppose it's impressive that you find that kind of time, but I can assure you that I don't have time to do that AND play a game or two. I'm glad you've never purchased something that you consider a "dud", but making the argument that anyone who doesn't extensively research a video game before purchasing it is automatically wrong for wanting their money back for making a digital purchase is a terrible argument.
