I've made a lot of bad decisions buying games over the past few years. I was able to fix most of them via quick trade-ins but many stuck.
- I bought Midnight Club 2 and hated it so I traded that in for James Bond: Everything or Nothing
- Bought Ninja Gaiden 2 and severely underestimated my skill and refused to spam Flying Swallow so I traded that in for Rainbow Six: Vegas 2
- Bought a Gamecube and Super Mario Sunshine. Despite being pretty fun, I ended up returning it for a PS2 and MGS 2.
The only lasting games that I hate having around are Rise to Honor (which is a dumb game that I got because I liked Jet Li), SOCOM: Combined Assault (super disappointing after SOCOM 3) and SSX: On Tour (fun but not near the level of SSX 3 and Tricky).
