Really, my answer depends on what you prefer. I mean the type of game. From reading this post, I got a sense that you like many different types of games. So broadly, do you prefer fps's, or somewhat classics, like mario and zelda? If both, I would go for a computer, mainly fps's computer or xbox, and classics Wii U. They all have their advantages, but one great thing about computers is that it has a much broader range of games than the other two. Sorry I couldn't help more, but it really all depends on what games you like most, as all three have somewhat generalized game types.
