I've downloaded games for my kid's DS on occasion. He's also got about 30 bought games, which he hardly ever plays.
£30 a time for these crappy little games is ridiculous (definitely to me, who can't stand the waste of time that is "gaming").
So what you're saying is that you bought a load of bad games, at full price, without even finding out what they are about. And they should be cheaper.
Two things really
1) they are cheaper - only a sucker pays £30 for a game except for the latest big game on the day of release. Most of my games (except for Zelda etc. that I had to buy straight away) cost under £20. Mostly new, although I have picked up a few 2nd hand ones.
2) I think you don't appreciate how much work goes into some of these games - things like Zelda have teams of 50+ people working on them, the cost is well into the millions of pounds, and there's only so many games they can sell (about 50 million maximum currently), so for games like that £30 seems pretty fair really.
It is depressing how people can completely write off a whole genre of stuff just because they don't understand it though - if I said "I can't stand those crappy little movies", or "I hate those crappy little books", people would think I was pretty stupid no?
