This is such a good point, I thought I'd quote it again. And an even better one. It's a puzzle, a new one every week. I never thought I'd even play this mode, but when I saw the scores and started to play I found it actually addictive. It has actually helped my overall game skill, like playing scenario's have. Learning sometimes requires losing. The Leaderboards are just some numbers, and if numbers were so much fun, we'd be all play with calculators.
