Well, in the end, Anti-Aliasing does basically the same. You take multiple samples for each pixel, all with a slightly different offset, and average the result. That way, sub-pixels on the edge of things will be smoothed out a bit. Rendering in higher resolution has a similar effect, since the minification onto the screen resolution usually averages multiple pixels into a single one, which is the same basic technique.
The reason why higher resolution sometimes work better is because you can take an about 1.5 or so bigger display and scale down, while AA usually starts at 2
Bottom line, it works (usually)
I don't need luck, I have ammo.
