I've only played for 37 hours, but that was enough time for me to complete this game plenty of times. No matter how many times I play this game, I will always enjoy it. Unfortunately it is pretty short having only 19 test chambers, but the ending was so unexpected and exciting when i first played! I won't spoil it just in-case you haven't played this game (why haven't you already its like 14 years old and its one of the best games ever made)

I just completed all of the achievements in this game so I don't know if I will ever return but, this is one of my favourite games ever and I really hope Portal 3 comes out in my lifetime. Well done Valve.
