I hear ya! I got to the desert area and it just felt like the game had run out of new stuff. That's fine in a lot of games, but I guess I didn't love the previous area enough to do it all again. Still, I adore all of the tiny tools and mechanics in Metro games.
Exactly so! The desert appears to be my final resting place as well. Oh well, I suppose the my digital corpse will keep the post apocalyptic "circle of life" rolling along...
