Alright, I thought I'd do this. ^^ I've mainly played handhelds though, so I don't really know that much about the PS and NES platforms. :p
GBC: Pokemon Gold/Silver/Crystal"Surf", "Violet City", "Azealea Town", and all the awesome battle themes...need I say more? There was no competition here xD
GBA: Zelda: The Minish CapEeyup, I don't think it is RSE. RSE will hold a place in my heart very dear to me, but when it comes to the quality of compositions and the sounds, this game just beats it in every way possible except melodic intricacy. "Cloud Tops" is absolutely frikkin majestic, and you didn't think a track like that could fit into a device barely able to fit in your palm. Then again, it was released towards the end of the GBA era, soo...
DS: Pokemon Diamond/Pearl/PlatinumThis OST is just insane haha. The game was pretty awesome, but this soundtrack got young me interested in VGM and all the technical bits behind it. So this is a definite one. I think BW was a very close second though ^^
3DS: Fire Emblem Fates? xDHow has no one mentioned this game yet? xD I haven't played the game, but oh my god this soundtrack is legendary. I've seen the way the music just seamlessly transitions during battle, i've listened reaaaally closely to those dense orchestral tracks, and every time I listen harder, it gets more rewarding. Plus, "Lost in Thoughts All Alone" is in it. PSMD is a pretty close second.
SNES: Chrono TriggerI kinda liked the Earthbound OST, I really loved the FFVI OST, I kinda enjoyed most of the rest (FE4 ahaha welp)...but when it comes to the sheer depth of ideas and creativity, nothing beats Chrono Trigger. Sure the sounds weren't fantastic - FFVI was much cleaner, but dang. There's just so much melodic development in Chrono Trigger. And it's awesome
Nintendo Wii: SMG1Yeah, okay. SMG2 was kickass as well, but it didn't have melodies as awe-inspiring as "Gusty Garden Galaxy" and "Good Egg Galaxy". This game's soundtrack broke the market for the next generation of games, setting the benchmark so high that even right now, I don't think I've found an OST as expansive and amazing as this one.
PS1/PS2: Kingdom Hearts? :pWait, does no one else adore the KH soundtrack here? xD It's diverse, memorable, and perhaps just slightly overdone when it comes to recurring melodic ideas. But those harmonies are beautiful, those soundscapes are beautiful, and I think no other game uses a piano better less Eternal Sonata. Chrono Cross is pretty awesome too though, i will admit ^^
PS3: Gears of War 3? xDI'm not sure how many people play shooters and love them here...but this game really nailed its music hard. Not just the "Mad World" reduction when the saddest part of the story hits - the main theme is orchestrated into a brilliant fanfare of horns, the choirs sound like they're coming for your soul...it's amazing. I don't think the soundtrack works that well in isolation from the game, but it's still really well done
