I think you missed my point. I also didn't say that there weren't exclusives that were worth playing, or that owning the other consoles wasn't a good idea. I said that the best console to offset the type of games available on a PC would be the Wii U (or other Nintendo system) purely because the typical types of games available are very much different (other than some multiplatform ports) than what's on it, and the other consoles. We don't need to get as granular as any specific game here. If you want to take a break from PC gaming once in a while, but still want to game, I still don't think there is a better way, or a way that contrasts more than Nintendo. That's my opinion of course, but I see it echoed very frequently. PC/Wii U combo covers a lot of ground. The other consoles have their places too, I just wouldn't say you're going to get a vastly different experience from a PC on them other than controller type (and as you mentioned) differing communities for some types of games.
PC + Nintendo is the best combo I agree 100%. Add in handheld gaming and you have some mighty fine entertainment.
