Quite. Usually when I see most traditional sports, TV, movie, cartoon, game show, kiddy game types or something of that sort that is not a unique intellectual property or based in video games originally, then I will almost certainly pass without a second thought, no matter how cheaply it's priced. Most of the time when I look at a selection of games for sale, I always mentally filter out all of that stuff, like it's not even real video games just a lot of shovelware junk with usually a few "real games" in the mix that might grab my attention. Most of the time though it's "all crap" and nothing worth a second glance.
However, I am not totally anti-shovelware. Just when the subject matter is lame or boring. Some shovelware actually piques my interest, when it's based on a unique or interesting concept or it's own universe. Those kinds of shovelware games, I will usually consider. Now that you mention it, I do like some Wii shovelware and some of the more casual titles, but I am still choosy about which ones. But because I am not a fan of things like Iron Man for example, I have no desire to play games based on that and usually the quality of such games are not so good. The GP picks them up because they are names that they recognize, and not because the game is good.
I'm even more picky when it comes to the condition. Even if it's a great title, and the price is a great deal, I'll probably still pass because I prefer near mint, if not brand new. Most used games are not near mint, or even close. Hell, some brand new games aren't even mint.
If it's a good deal on a good title that I already own, I'd only consider buying if the condition is actually better than the one I already own. Otherwise, pass.
So although it may seem like I am not, I am very picky. Most of the time, I won't buy unless it's exactly what I'm looking for.
