I played this game when it came out 25 years ago. It was an absolutely phenomenal experience. I have since played this game through three times as the years passed by, and every time it was brilliant game. I can only recommend it.
I played the original when it came out, but while innovative and phenomenal in general, it was too hard to play. The way you moved around was too complex. This game, with updated graphics and game play is a a treat. I can say that this version of the game is one of the best first person RPGs ever made.
