i love the old snes soundtracks,like the music in terranigma. I'd definatly go with odst. but a moment that was affecting me very much was at the end of portal 2 where the turrets start singing . that was amazing.also the music in okami made the game even more special for me
The Orchestrated Soundtrack CD that came with 'The Legend of Zelda: Skyward Sword' Defiantly amazing to hear all those old Tunes redone with the use of a Full Orchestra Especially the Gerudo Valley Theme: www.youtube.com/watch?v=THdRs7grqhE (The Louder you set the Volume at, The better It Gets)
Always have loved the Zelda and Halo soundtracks. However the Splinter Cell: Chaos Theory soundtrack has always stuck with me. I think its just really well done in the sense that its effective. The sneaking music is calm, yet gives off a sense of danger and being on the edge. And the action music is effective yet not over the top. For a game that came out in 2005, I am still impressed by it.
