I actually went back and played this one last year, and it still is a good game.
If you turned Lara into Larry, it would still be a very fun game to play. You have a fairly open environment, some cool puzzles, a pretty weird storyline, a trial and error type of jumping around rocks, a big ol dino, and ah that infinite ammo.
That aside, the graphics look really angular, but when it came out for the PS, they were amazing! Slight sarcasm intended.
This started the legacy, and I still feel that this might be one of the best of the series, though I haven't tried out the update version. Well, nothing can be any worse than Angel of Darkness.
