Oh I forgot to mention, it says "Only on PlayStation" on each collection's cover box art, at the top-right side, which means "PS-exclusive". So sorry :D
You're pretty much the only pathetic PC fanboy begging for ports, I haven't seen any other PC gamer asking for PC ports of KH on any video or forum I've been.
Instead of wasting so much money on upgrading your PC hardware and all that unnecessary stuff you should save for a PS4 when it goes on sale and you'll be able to get to play all this good games instead of keep playing crappy low budget indie stuff on steam, which 95% of steam catalogue is.
You can see the majority of developers and Square Enix doesn't see PC as a big priority for them due to the fact that every game you mentioned is either not getting a PC port until years later or not getting one at all LOL
