Of the three you listed, I prefer Uncharted considerably more than the other two.
However, it doesn't meet two of your criteria, and the third criterion is met by all three games so it is pretty much moot.
Personally, I had gotten pretty bored of LBP relatively quickly. I guess it depends really how much you play online as that seemed to be the biggest attraction. It was incredibly charming though and was certainly an unforgettable gaming experience while the fun lasted.
Infamous, I'm not sure. It wasn't on my radar much until I tried out the demo. I thought it was a blast.
My advice: try both the Infamous demo and the Uncharted demo (if still available) and go from there.
