There should be a Nuzlocke Category for TABS. In this category, speedrunners would attempt to complete as many levels as possible, starting in The Introduction, then continuing through each campaign. Every time a unit dies in their army, they can no longer use that unit. Their run ends when all units are no longer available to use, if they complete all non-user-made campains, or if they get a PriceLock(they can't afford any non-nuzlocked units in that level). They are not allowed to use any secret units, ever. The leaderboard would show how many levels they can complete, so the first place spot would be to the person who has completed the most levels. Moreover, if multiple people have (somehow) completed all levels, then whoever did it fastest would have the first place spot.

 Does anyone else think this is a good idea?

It sounds quite fun, I can create leaderboards that sort from 'slowest' to 'fastest' as well to simplify things. I desperately don't want to overpopulate boards, it's already heading a bit that way with full game categories constantly having to be updated or changed, so I'll come back to this idea if a few people like your post (who have a genuine interest in running this), or there's further interest from other runners.
