So with the max completion % now being 109 with the DLC, how would that affect the 100% category? Like could you do some of the DLC and skip out on some of the base game to still get 100%? Or would 109% be a separate category and 100% had to be ran on a pre-DLC version.

We could make a 109% run category. Ideally if you wanted to run without DLC, you can just untick it in the Steam settings IIRC?

We could have a 100% (no pit of the damned) and a 109%. I'm not opposed to it but the fact of the matter is no one is even running any% let alone 100% at the moment. I'm also not too interested in verifying 12h+ runs myself.

I've always been of the opinion that an "all mirror fragments" category would be more interesting than a pure 100%(109%).

I like the idea there Merkie! Definitely feel free to spruce up the boards a bit as those are good ideas for sure
