Not much to say about this game that hasn't already been said elsewhere. Flawless execution all around. One of the best developers of all time involved with it. One of the best examples of level design, any genre. Amazing both ambiant and heart pounding soundtrack and sound effects. Inspired an entire genre that has steadily become one if not the most popular. So unaffected by time, that as years pass it becomes more and more fun the more times you play it. Has a new iteration that has been 10 years awaited which I have stated several times, if it sucks I might quit gaming and sell all my gear! HAHA
