So a new Armored Core came out about a month ago, and now that the dust has settled, I'm gonna give it a little review:
First off, it's SO much better than ACV. I thought that game was good, but this one blows it out of the water. Almost every single problem was fixed, and there's still so much more content. AC development has improved, the missions are better, the music is kickass, the framerate is actually respectable now, and bosses are as a challenging as ever.
I might be alone when I say this, but I consider it GOTY.
