I don't understand the Small World suggestion. Honestly, Cosmic is so different from most games I'm having a hard time naming a similar one.
I'm a little surprised at your bafflement; it doesn't translate directly at all, but there are variable powers for each faction that change from game to game.
Age of Gods has a lot of overlap with CE as well - a special power for each player that changes from game to game and cards that affect combat and offer special advantages.
And War on Terror doesn't have special powers, but it does have 2 decks with special effects and the kind of highly chaotic, constantly and rapidly changing, 'anything goes' environment that defined CE. For that matter, their new release Crunch: The Game for Utter Bankers has all that as well.
