Metroid Prime - I got too bored, and got distracted by Ninja Gaiden and KOTOR
Ninja Gaiden - The pink flying demon lady (I can't remember her name) is too hard for me
Final Fantasy: Crystal Chronicles - Worst FF EVER!
Final Fantasy VIII - Adel is too hard for me on my file there, and now the disc keeps pausing whenever I get up to the last battle with Seifer
Conker's Pocket Tales - I lost it a few years back
Baldur's Gate: Dark Alliance - I played the sequel beforehand and thought it was better than the first
Second Sight - One of the levels just proved to be too hard for me
Psi-Ops - Same thing as Second Sight
Vectorman - Same as the last two
Harry Potter and the Sorcerer's Stone (GBA) - Too boring
Various other games I forget the names of...
