I bought Game Music Bundles.

Was a huge Jesper Kyd fanboy once and own most of his soundtracks plus a few other ones. All of them are on CD except for Assassin's Creed 1 & 2 which were Amazon downloads and BioShock which came along on a vinyl record included with the limited edition of BioShock 2 (which I specifically bought for the soundtracks).

Alien Nations OST
Assassin's Creed OST
Assassin's Creed 2 OST
Best of the Best (exclusive pieces done by many different famous game composers)
BioShock 1 & 2 OSTs
BruteForce
Freedom Fighters OST
Hitman 1 & 2 OSTs
Hitman: Contracts OST
Hitman: Blood Money OST
Immortal (compilation of several Amiga soundtracks re-done by their original composers)
Immortal 3 (see above)
Immortal 4 (see above)
MDK OST
Robotech Invasion OST
Shades (Chris Hülsbeck's first album including some themes from his Amiga soundtracks)
Symphonic Shades (live orchestral concert of various pieces by Chris Hülsbeck)
Stubbs the Zombie OST (actually just a compilation album - a pretty good one, though)

Probably forgetting a few entries. Also looking at this list makes me sad because I don't think I'll ever get Immortal 2 which is sold out and out of print. ;(

Final fantasy 6, 7, 8, 9, 10.
Guild wars
Morrowind
Guilty gear X and XX

I bought the FF7 piano collections as well.

Alone in the Dark (the last one) by Olivier Deriviere

The game is awful and beyond broken but I really like the OST.

It's kind of sad when I think of it, Olivier Deriviere is pretty talented but all the games he did the music for (this one and Obscure 2 IRC) kind of flopped, it would be great to have him make the music a successful game for a change.

I bought deluxe edition in Far cry 3 and it said it has soundtract. it didn't so asked about in gamers gate support, they never answered.. Well it was originally that I need those deluxe editions but it seems that they had already included that but where is my soundtrack. Usually gamers gate answer a lot, now.. I get nothing.

I give anything to buy the OST to Metroid games listen to this hidden gem from Metroid Prime 3'

I just bought the 1st Drakensang OST for $8.99. I love the "medieval" tune of Ferdok.

I bought the Alone in the Dark soundtrack and the Halo 3 soundtrack. Don't regret either one. I would also buy the Final Fantasy XIII soundtrack if it weren't for the fact that it's pretty expensive. Apparently, it wasn't released in the US, so I could only get an import.

Well, I plan on getting around to buying the Botanicula OST eventually. I also bought the other albums by the band who did the OST, but I suppose that doesn't count.

Oh, right, those too. Like you I really just bought the game for the soundtracks (haven't so much as installed the game, and I don't even have the first one). Not sure paying for the CE of a game would be considered paying "roughly normal price" for two soundtracks though (even if it was cheap, can't remember the price now though).

This is why I think GOG should sell soundtracks here for games that are already here, like with the bundling. Music is important to people.

Bayonetta (CD-set from some Asian webstore)
Venice Rooftops and Ezio's Family from Assassin's Creed: 2 (iTunes)
Assassin's Creed: Brotherhood (CD from eBay, had been a part of a special edition)
The two 'Old Gods' songs from Alan Wake (Poets of the Fall webstore or somesuch)

Some time ago I also ordered the Skyrim soundtrack, but it's either slow coming or then it got lost in mail.

The Seventh Guest (and used it as horror-movie music)

DSA - Nordlandtrilogie (Realms of Arkania, great background music for Pen&Paper RPG sessions)

And I would have paid for the music from the later Ultimas, especially that from the remake Lazarus, but that's free anyhow.

Just the Zelda orchestral stuff. But I will probably pay for Elder Scrolls music eventually.
