Taken from the website: "NEOTOKYO is a first person shooter that provides a visceral & realistic combat experience in a rich futuristic setting. It is greatly influenced by our admiration for Masamune Shirow (GHOST IN THE SHELL) and Katsuhiro Otomo (AKIRA), and has been in production since October 2004." Developed in the Source engine, Neotokyo is a hard-as-nails competitive multiplayer shooter. After a quick google, Ghost in the Shell and Akira both appear to be animes. I'm not a fan of anime, and I don't really see any anime influences in-game; but I think the developers just used the animes as inspiration for the setting of the game.

Now, I haven't heard ANY of the soundtrack in the game, besides one song on the menu. This is odd, especially since there is two and a half hours of it.
Since this OST is so long, I recommend that you use it as backround sound as you play a game, then tab out and favorite individual songs that you like during your game. Planetside 2, Interstellar Marines, or practically any other game set in the future should fit the bill.
I'd tell you what my favorite song was, but all the songs progress so differently. I feel I should warn you that, in my opinion, most of the songs suck in the beginning. Later on, the songs progress into something that feels much more complete, and enjoyable. Some songs use the same resources, but I feel that each song is individual enough to get away with that. If I tell you a song I like, you'll skip to it and say "Wow, this isn't very good" or "This doesn't progress very well" or something, but if you stick around to listen to some others, you'll really like some. Probably. No guarantees; after all, this is music.
