I once chose to purchase Sonic Riders (GC) over Super Smash Bros Melee. I was young and innocent, I am sorry.

What were your worst mistakes?

Also, let us keep this trolling free, pretty please.

Buying Duke Nukem Forever cause of the hype... I regret it ever since... Its like AIDS on my steam library

Traded The Legend of Zelda: A Link to the Past for Tom & Jerry.

Buying the LE of FF XIII.
63 fucking quid (plus shipping) for a game I hated through and through.

Wasting all my allowance in a stupid Tazmanian game for the GC...Taz Wanted...never forget...

I bought Eternal Sonata because a friend said it was good. I never regreted something as much as that gaming purchase... I hated that game with a passion. It was boring as hell and it was the only game I had for my PS3 in a whole year. I ended up selling the game last year though!

Traded in my entire PS2 collection, thats like 40+ games =(
Not my decision but my mum gave away my N64 collection one day when I was at school... thats costing me thousands to get back now -_-

I personally enjoyed the game,even with the outdated graphics.

WiiU

Darksiders 2....played for 2 hours....didnt like it....first one was much better

Fortunately, I never made any decisions I regreted later on.

BUT... but... my brother chose Lamborghini on N64 over F-Zero X...
