I played the first metro and enjoyed it. Not a stellar game (Like Farcry, Halo etc) but a solid FPS. Graphics were good, cool options to have the whole game spoken in Russian (with english subtitles). Biggest problem, the game was too dark. I adjusted my TV to the brightest setting and i did the same with the console, still it was overbearing. This, coupled with the annoying cracking and constant cleaning of your mask mid combat made visuals very un-enjoyable (especially on the hardest difficulty, straight up chaos)
TL;DR Good story line, cool apocalyptic theme and weapons, ruined by low visibility and shoddy combat interface.
I really enjoyed the stealthy part of the game the moving through tunnels and sneaking up on enemies. Didn't like being rushed through parts of the game and the ending left me thinking what thats it? Overall it was a good game but it just left me wanting, 7 bars for this one.
