We picked up Lego Batman yesterday, and I have to say that this is more what a video game should be like. This game knows it's cheesy, and loves it. The priority for Traveler's Tales was obviously to make it fun, not to make it difficult. Don't get me wrong, I enjoy a good immersive game, but it's nice to just play sometimes.
What has been great for me is the two player mode. You don't end up dragging each other around quite like the older Lego games did, so it's actually quite fun to have a second person join in (in this case, my wife).
Sure, there have been a few times that either me or my wife have yelled at the TV, but it wasn't one of those "Bad game designer, no Twinkie!" things. It was "Harley, quit jumping around so I can smack you!"
