I just finished Metro 2033 Redux last night, and now I'm playing through Metro Last Light Redux. I don't have any past experience to compare Last Light too since I never played the original, but 2033 Redux is really surprisingly good. I was already a big fan of the original game, but the remaster really nails everything the original slipped up on (except the stealth is still pretty bad, I never even attempted it with this playthrough). Last Light however, is even better somehow, they both feel like grand odysseys more than anything, and take full advantage of the fact they're post-nuclear apocalypse. The supernatural elements are still really well done, I even got chills during one sequence. Highly recommend both of them if you want a pair of good shooters or good post-apocalypse fiction.
