Metro Last Light

I have played these games and there is a new one coming out in a few days, I have it on pre order.
Anyone else played it and found any other games that are similar?

I played the first one (and completed it several times). It was good, but not good enough for me to invest in the sequels...

Surprised a game is good enough to play several times but not good enough to buy the sequel only games I have played more than once are ones I have loved and would buy the sequel without a second thought.
