Since we're all giving our opinions on the game....
I thought it was excellent. The game play could've used more depth though. The world, atmosphere, and story are second to none. I really loved the city in the sky, and the music was especially engrossing. Few games give me chills like a movie, and that opening is worth the price of admission alone. Once you hit Columbia, and the subtle piano tune, followed by the hymn kicks in, I'm there. It's such a good opening. One of the best cinematic openings to any game I can think of. It's so good, and the impact lingers and makes an otherwise run of the mill shooter, special.
That said, it does tend to overstay it's welcome a bit, simply because the game play is so familiar. It's an arena shooter with some very basic RPG elements, and it does nothing special in that regard. I would've appreciated a little more effort in that department. The game play is nothing special. Once you get settled in, you're pretty much shooting shit and opening drawers.
I'd give it a 6/10 in the game play department, but a 10/10 in the story/atmosphere department. That's all you can ask from shooters. It's hard to re-invent the wheel, but if you give me something compelling to shoot my way through, I'm good. The story wasn't "tight", but it was compelling, and left you asking questions in a good way. And seriously, who didn't love the big reveal? It was no "Would You Kindly?", but it did the job just fine.
I loved the game. TLOU rightly overshadowed it a bit, but Irrational Games still went out with quite a bang with this sucker.
