A lot of us are guilty of buying a game we didn't like one point or another and to some it may happen more frequently than others. Maybe you were just young and didn't understand the game was bad or maybe the game wasn't even bad but you just couldn't get into it, or maybe you're lucky and haven't faced this problem before.
Personally, the first game I regretted buying was a Jurrasic Park game on the GBA. I was 9 years old at the time and up until that point hadn't played a game that I didn't find fun. Well, I bought this particular game to find out it was a weird collecting game where you were a character that collected colored orbs and avoided dinosaurs (I think). It was very repetitive and boring. I returned it a few days later when I could... 
How about you guys?
