Leaderboard: What's your favorite player-generated content tool?

Leaderboard - What's your favorite player-generated content tool?
Neverwinter recently launched, and Cryptic's Forgotten Realms MMO brought with it a substantial player-generated content toolset called the Foundry. The Foundry isn't the first of its kind, however, or even the first of its name. Star Trek Online boasts an earlier version of Cryptic's Foundry, and other games going back a decade or more have also tried their hand at user content suites.

Assuming you've played around with a few of these tools, which one is your favorite? Vote after the cut!

Ever wish that you could put to rest a long-standing MMO debate once and for all? Then welcome to the battle royal of Massively's Leaderboard, where two sides enter the pit o' judgment -- and only one leaves. Vote to make your opinion known, and see whether your choice tops the Leaderboard! %Poll-82393%
