Techno has been sadly misused in computer games, a lot of games will use "technoesque" music which is just techno thats been so heavily watered down it's lost all it's flavour which makes it techno. Just take any tecno track you lie and turn it into a four bar loop repeated endlessly and you get the idea. There is only one game I can think of thats stuck in a blasting techno track and just let it run, and thats Rez with the Ken Ishii track which was easily the best track in that game.

Similarly I think it's too easy for a game to sell out to commercial music as this is clearly going to increase their sales since it's something popular already to build on. Look at two games, the utterly amazing Frequency and it's sequel Amplitude. Frequency featured about twent tracks from a variety of bands and genres, most bordering on the publicly acceptable ranges so you had a bit of No Doubt as they were were well known, a few hip hop, some thrash metal guitar type tunes and a few dance ones. It's sequel Amplitude I have almost no desire to play as the tracks on that sound awful with a cash cow of commercial tat cash in. I mean the first game didn't even feature any tracks that interested me but the game made the tracks tolerable. Putting some proper stomping techno into a game like Frequency would make for one of probably the most sublime gaming expereiences I can imagine.

I think the other problem with techno music in games is techno itself has some negative associations with it, drugs, drink, violence and all the other cliches the popular press pull out of hat whenever they need to do something bad. These days a lot of games want to appear kidlike in some form another so they can appeal to all ages, techno music is the sort of thing which is going to tarnish this image.

Finally, it never stopped me playing techno in games anyway. I remember a lot of joy playing Battlefield 1942 with some Daniel Benavente sets firing on the backgroud as you sneak about over hills and strafe bomb tanks or sticking on some Adam Beyer mixes whilst playing Enemy Territory.
