The Crimson Binome
Hero
Based mostly on listening to the System Mastery podcast, the top runners that I'm aware of for at-the-table complexity are Synnibarr (which has every rule ever in it) and Living Steel (which is the RPG counterpart to Phoenix Command). Nephilim (mentioned in a previous post) is probably not in the top three.
Honorable mentions go to the old DC Heroes game, The Great War of Magellan, and first edition Skyrealms of Jorune.
