The first time I've ever played Another World was on my 486, I remember I booted up the game and wow, I was so shocked at how "cinematic" it felt, it looked and played like an animated sci-fi movie, fluid animations, always unique enemies, action puzzles... I remember it was the first game I've ever played that needed you to actually run away from the beast at the end of the first level instead of just shooting the hell out of your enemies. The world around Lester felt more alive than every game I've ever played before and Lester himself was a true human, not some sort of pumped superdude with a shotgun.
Smooth animations like I was never able to see from Prince of Persia times, glorious and fascinating graphics, rapid action sequences and an hard yet satisfying gameplay.
When I played this remade version for the first time I had a similar feeling, It wasn't something new, I've played this game dozen of times during years, but the sharp vector graphics i was able too see as child on my old crt monitor looked pixelly on my new 23" LCD, this restyle reminds me more than the original version how I used to look at this game, I know it may sound strange but it's true.
And yay, no more passwords to remember :)
This game made my childhood and it's one of the best games EVER.
