More or less. There's only a few games out there that I haven't finished or never will finish, purely because I didn't enjoy them or I borrowed them and decided they weren't worth buying. The few of these games that I remember would be Legacy of Kane: Soul Reaver, Centipede and Shadowgunner, all for the PS1.
On the overall, there's plenty of games I haven't finished, but I do intend to finish them.
