I would disagree strongly on that and so would nearly everyone I know. I've had my second cousins sit down and play older games (they asked me what gaming was like when I first started) and I have to say that compared to newer games, the older AtariIf your other choice was an XBone, that kind of disqualifies any opinion that follows it from being rational.
Outside of that, clearly the game mechanics and user interface are always more important than the resolution, etc... I could still argue that games from the 1980s (like Defender) are a lot more fun than many of the games made today, despite very primitive visuals. So, if you prefer the Wii U, despite having clearly inferior hardware, its completely understandable. Everyone has different taste.
