You're very much welcome, I'm very happy to see people taking an interest in this. You've made some great recommendations too, Perfect Dark was especially outstanding for an N64 game. Come to think of it all of Rare's games (Perfect Dark, Goldeneye, Starfox Adventures, Jet Force Gemini, etc.) have great music and the company itself is based in the UK so obtaining the games shouldn't be much of a problem (as sound track cds unfortunately were not made for all of their titles).
Now that you mention it in fact I recall playing Shadow Watch through to completion JUST because I enjoyed the score so much. My fetish for turn based strategy games no doubt helped but the sound track is definitely the highlight of the game. Best $3 I ever spent on a bargain bin purchase. The MGS theme I agree is an experience NO ONE should be without! I'm surprised I didn't think of it earlier as it's such a popular franchise these days. Great call.
It's a shame it must be so difficult to obtain the actual sound track cds for many of these games in the UK. I'm a US resident myself but given the relatively minor prenetration game music has made into "real" music stores here I can't imagine how bad it must be there where many of the games won't even be released. One item UK residents shouldn't miss out on however is the Silent Hill games. Silent Hill 2 sold exceptionally well there, causing the sound track and other bits of it to get an official release there. Silent Hill 3 was even released in Europe FIRST, then in Japan, and finally here in the US just two weeks ago. A sound track CD is included with the game, fantastic horror sound track if you ask me.
I agree too that making your own cd compilations of these songs is definitely the way to go, especially when many of the songs will HAVE to be found via file sharing programs in the first place. I don't know what the policy is about discussing such things on this site but if people want some samples of the games I listed in my previous post I'll be on a much faster connection in the next few weeks so I'd be happy to send out a few.
