Fallout: Brotherhood of Steel (X-Box).
I never owned it, but I did rent and play it... It's probably the most upset a game has ever made me regarding the treatment of a franchise I've held dear.
Worst game I OWN... (neverminding stuff that came bundled in steam deals)...
Probably Star Wars: Rebel Assault II (1995)... Non canon, "Full Motion Video", rail shooter WIN 95 CDROM.
I think I got it as a gift... I know I didn't seek it out, but I still have it lying around, 17 tears later...
Around the same time, I played a 4x strategy game about asteroid mining colonies called Fragile Allegiance, which I really enjoyed and had some cool ideas, but was a literally broken game in retrospect - you could not win: the victory conditions were unattainable for a whole slew of correlated reasons that only become apparent once you delved in deep. Still fun, mind.
Manhunt 2 on PC is garbage. It delivers on the depraved hideousness that is it's selling point, but mechanically it's just frustrating, dull, buggy and unresponsive.
