I thought Last Light was actually better than 2033 myself. If you got it I'd say keep going

I dunno.. I myself hated it.. but that doesn't mean that you will.

Last light improved many dynamics from the first game. A more in depth storyline, side missions, newer weapons, tougher enemies, and more survival oriented when you hit the surface. Also your actions I'm last light effect the ending. Sorta like silent hill there's a good ending and a bad ending. Its worth at least a look.
