Needlessly Complicated Legends got over a thousand downloads, and I think it was in the best of AOW2H section for a while, so it can't be that obscure. But for this map, you probably won't need to know much about NCL to play.
Simplified Legends takes four wizards from NCL, and 18 heroes, and throws them into a really condensed version of the world, with some neat scripts and very little room. Also, it's my first map with the uPatch(yay!:D), and I'd like to think it looks as good as NCL did. Though it probably doesn't... I kinda rushed the terrain a bit... but it's a small map. You'll never notice!
One last thing(promise!) The AI is actually better at this map than I thought it would be. Playing co-op against 'em might work, I don't really know... but I'm gonna assume it doesn't. And the AI won't be able to use Black Helmet Man's scripted weapons.
