Personally, I don't think the really big ones are good for speed runs at all. But maybe having some 5x5 and 3x3 size categories could be fun.
Because those aren't insanely big or insanely small, and still allow for actual gameplay to happen.
They could each have their own subcategory?
The original game was 4 x 4, so should be the main category.
After that, I see no reason their can't be a category for each variation, as they each have their own level of ease or difficulty in regards to size.
But beating the bigger ones is not getting a 2048 tile. To beat a bigger one you have to get a bigger tile depending on how big it is.
And for 3x3 to beat it you get either a 128 or a 256, we could have a category for each.
There's tons of sizes, really. But the ones I think we should have are 3x3, 4x4 (obviously, thats just the main game), 5x5, and MAYBE 6x6.
