firstly, what are some of the many western AAA games that feature "generic rip offs of o fortuna"? while also keeping in mind that an o fortuna type piece may in fact suit a game's aesthetic! your spiel about "unreasonable deadlines" just comes across as nonsensical jabbering from someone who doesn't know what they're talking about. re, tomb raider 2013--how come that game isn't just one with a bland soundtrack and not some agent towards your confirmation bias about western AAA gaming music? i don't suffer through motoi sakuraba's second-rate tales soundtracks and claim that most japanese game music is rife with van halen synthesizer leads and awful midi orchestra samples.
I gave you an example, Tomb Raider 2013. If you'd like more, I'd also cite the music from the Arkham games and Assassin's Creed series as nondescript and forgettable to me. You may disagree and like the music in those games, opinions and all that. To me those soundtracks sound like forgettable generic Hollywood background music, or in Arkham's case, like generic Hollywood Batman music. And I like Tomb Raider 2013 and Arkham Asylum! But not their soundtracks.
I fully admit that I am not a big fan or connoisseur of western AAA games and haven't played as many as you. My point is based upon what I have played and, in a limited sample size, I've had similar reaction to the OP. I'm not trying to make some grand generalization about western vs eastern games, but an observation on the ones I've played. At the same time, you shouldn't have to be an expert and play dozens of games in a particular genre to have an opinion. This is supposed to be a fun gaming message board where people with different tastes can share their opinions. You may be an expert on, I don't know, FPS', but you should also get to share your opinion on Puzzle games even if you don't play them that much. Also my point on deadlines was merely a theory and I stated as much in the post. Theories are fine as long as you describe them as such. Again, this is supposed to be a fun message board where we exchange information and (documented) speculation. If we can't share theories, then shit, what is this? A quiz bowl to see who can remember the most facts the quickest?
So I'll try to take the high road here again and say I stand by my opinion for the reasons stated. My personal experience with AAA western soundtracks is similar to the OP here, although it is by no means a generalization of all AAA western soundtracks. And again thanks for contributing that list of songs, it's a very good rebuttal.
