Why 0% and not Low%? As far as I understand, games that have Low% don't restrict you to a certain number of items, they just prioritize number of items over time. So, someone who beats the game with 0% of items in 3 hours will be in the lead compared to someone who beats the game with 1% of items in 2 hours.

0% raises the barrier to entry, which is probably why the category doesn't have a lot of activity right now.

NG+ is locked on Knightmare difficulty.

Should there be any restrictions on what equipment you can or must start with? I suppose if you do enough AR challenges, you could level up Batman pretty high before starting NG+. Also, DLCs allow you to level up even further by completing more AR challenges beyond the base game.

If it's possible to share save games with this game, then maybe a fully maxed out Batman could be used as the starting point for all NG+ runs.

Any reason why there's no NG+ category?
