Such a small amount of games to choose from.
Not really? I named 9 fantastic games, and there are a few that I haven't played yet. I haven't played Captain Toad or Tropical Freeze, for example, which I've heard are both really good.
I'd argue that even if a console only has 5 true must-own titles, then it's a success. The Wii U has at least 5 must-own titles.
