Multiple games in same box using same components. What was it?
Sounds like Stonehenge: an anthology board game:

Stonehenge is an anthology board game, a new concept where five award-winning game designers, all using the same gaming components, create five very different games in one box. The ancient ruin of Stonehenge will never be the same. The five games are:

a magic game by Richard Garfield (Magic: The Gathering, RoboRally, The Great Dalmuti)
a political game by Bruno Faidutti (Mystery of the Abbey, Citadels, Knightmare Chess)
a battle game by Richard Borg (Battle Cry, Liar's Dice, Memoir '44)
an auction game by James Ernest (Kill Dr. Lucky, Diceland, Pirates of the Spanish Main)
a science-fiction game by Mike Selinker (Risk Godstorm, Pirates, Axis &amp; Allies Revised)
