lol, among you oldtimers, I have not done as well.
If I hadn't had that rough financial time, I'd still be sitting pretty on that beautiful CAVE Collection too ... an extra 37 albums of pure goodness (some more pure and goodly than others).
I keep my collection on vgmdb VERY accurate, thorough, and up-to-date. I also have it split digital and physical, so you know what's sitting on a shelf vs what's some bandcamp soundtrack on my HDD.
My physical collection shows at 198, just under 200 (it'll be at 200 once my SE albums Adventure of Mana & SaGa Orchestral arrive). That includes any album that vgmdb will list, so there are some chiptune and loosely-vgm-ish albums on there (at first glance I saw a Chipocrite CD and a Protomen album).
My digital collection, existing largely thanks to Humble Bundle and the Loudr VGM bundles, is at a whopping 377. Some stand-outs in that collection for me are those import soundtracks that never got physical releases (FF Dimensions, DODONPACHI MAXIMUM MBS Ver2.02 Soundtrack), and then ... tons of amazing indie soundtracks. The arrange albums too. I love the too "FZ" albums for FEZ, the Indie Game Mashup, Blocks That Matters' "Reworks That Matter," and "The Scythian Steppes" for Sword & Sworcery.
When I look at my physical collection, the only things I *really* want are the box sets that I will likely never be able to afford: Breath of Fire (11 discs), Wizardry (6 discs), Ar tonelico kurt hymneth (6 or 7 discs?), the stupidly large GUST box (44 discs). I'd have to be facing eviction to consider selling my current box sets: SaGa (20 discs, with the Disc 1 sleeve signed by Uematsu because FF Legend / Makaitoushi SaGa is one of my favorite Uematsu works!), Seiken Densetsu (18 discs), DQI-IX Symphonic Suite (10 discs), The Ys III / Felghana Box (8 discs), FFXI Premium Box (7 discs), Masaya / Langrisser I-III Box (6 discs).
(I'm also still very sour about Konami canceling the Suikoden box set...)
So yeah, that's me. About 200 physicals, most of them single or double disc, a handful of larger OSTs, and then those mega-boxes listed above.
EDIT/PS -- I am also marginally interested in this boxed set: http://vgmdb.net/album/55803 -- even though it has anime material and drama. I played this visual novel on Vita and WOW WOW WOW, this is excellent stuff. The music for it is great too, I've always loved Takeshi Abo (a 5pb regular, Ever17, Never7, etc). I want to play Steins;gate 0 very badly now, I hope it comes to the US relatively soon.
