Wow, we have 40% playing it more than five times? Awesome! Nice work guys. And they say Metro 2033 was flawed... like anyone plays a flawed game over 5 times!
Well, nothing is perfect, Metro 2033 has flaws just like all other games do... but there's so little of them in there and the whole experience is so amazing, that the game manages to earn the rating of 10/10 from me - the closest you can get to perfection in gaming.
I've played it I think four times just played it again and got the Enlightened ending. To be honest I feel like playing it again right now this time in Russian something different.
I'm currently on my 4th play through. Three out of four times I played it in English and right now in Russian.
