Sea Hunt. If you never tried it, I challenge you to score any points.
How did I forget this little doozy? Although I'm not sure if sloppy, poorly-programmed, borderline broken games should count. (But FWIW, I *can* score points in this game. )
How about Racquetball? I get what Apollo was going for with the ball shadows and such, but it's confusing to the point of unplayable. Plus I'm pretty sure the hit detection was a little whacked anyway.
Or E.T.? The standard variation of E.T. just aggravates me. No, not because of the pits (*sigh*)--it's because those FBI and Science dicks constantly kidnap me and steal my shit! Yes, I know how the zones work. Nevertheless, completing the game just once takes a miracle for me. It's much more enjoyable (IMO) on the other game variations that remove one or both of the human enemies.
