EB: In total this one little mission took me about 45-minutes, so it was a great sample of what to expect in the final version of the game. I found the experience to be a bit more challenging than I personally like for a FPS, but I also found it to be very true to the Metro franchise, so fans should be excited with what this more open-world version of a Metro game will offer. Plus, the whole traveling crafting mechanic is a Godsend, because being able to craft on the fly makes exploring so much more efficient, so that is one gameplay formula change I think both new and old fans will greatly appreciate.
