Isn't this a question of how we define "taste" though? I've seen some goods points made in this thread.
The purpose of a video game is generally for people to enjoy it, right? Regardless of how "broken" or "bad" it is there is always some people out there who are going to enjoy it. Therefore the game served its purpose? This is how I look at things, and usually don't divide things into bad or good. Of course in social occasions I'll state things like "this is so baaad" because I'm not that far up my own ass, but I basically see it as I either like something or I don't.
I used to be one of those people who thought I knew what made a movie good and what made it bad, that I had some secret knowledge of what works and what doesn't because I worked as a reviewer and made movies myself. I later realized that I don't know shit, and that no one really does. I like it or I don't, if someone else doesn't I'd love to have a conversation about why, but in the end it doesn't affect me. And I would never accuse that person of having "bad taste" because he had a different opinion.
I feel like I'm not adding a lot to the conversation here, but I was bored and had an opinion, so there you go.
