As for me, I can't think of any really bad games i've paid lots of money for. I only paid like 5 bucks for James Pond on the GBA, and that was still too much, not one good thing about that game.
Urban freaking Champion - the suckiest game that Nintendo ever made.
That makes me a sad panda. I hope you didn't spend months upon months saving up for that game.
Mine was Quest 64. It was so bad, I finally jumped ship and started saving up to buy a Playstation!
Probably $20 on Diddy Kong Racing DS,it's still not a terrible game,but it's probably one of the only games that didn't seem to be worth the money spent. Maybe if it controlled better,or the voices weren't so irritating.
It's worth $5 at the most,it's just not the original at all.
I'm usually too careful to make that kind of blunder,but once in a while it does happen.
Since I usually try to collect the best games of the console first before I experiment and take chances, I usually am pretty happy with what I get. I have gotten some horrible games in game bundles off of ebay when buying a new console. I purposefully have bought bad groups of games in order to get a console at a cheaper price, but I don't think that counts.
