If I buy Minecraft on a PS3 account, can I get it on the PC for free?

I've payed for and downloaded the game Minecraft on my Play Station 3. Is there anyway I can download it for free on my PC, I mean, I've already bought it. There must be a way to connect the accounts or something. And if I can't, would you please explain why?

Minecraft PS3 Edition or Dr Luigi?

It's all in the above question. I want to get both games but I can only afford one at the moment. I want to know which one you think I should get and your reasons why. I love Minecrqft on the PC but as my laptop isn't too good I can't play it very often. I also love the Dr Mario series and I'm quite good at them. Pricing isn't a problem as Minecraft is £12.99 and Dr Luigi is £13.49 so I don't care about the difference in price so don't use that as a reason. I do use my Wii U quite often but I don't use my PS3 much apart from watching blu-rays but I wouldn't mind bringing it upstairs to play on it. So which one do you think I should buy and why?

Is Final Fantasy: A Realm Reborn a good game?

I'm looking for another game that i can play long-term, like i do/did with minecraft and runescape. Would this be a good game like that?

and how is the game overall? I'm thinking about getting it for either the PS3, or waiting until it comes out on PS4 because i don't have a good enough PC for it.

what do you think? By the way, this is coming from a guy who hasn't played previous final fantasies.
