Ravenous Bugblatter Beast of Traal
Sorry, I'm not familiar with Twilight Struggle to rate it, but I do have some suggestions.  Castles of Burgundy, Puerto Rico and Xenon Profiteer are games I really enjoy that are a bit more complex with multiple winning strategies.  Carcassonne is simpler than Catan but no less enjoyable for that and requires good long-view tactics.  None of them are at their best with only two players though.  The Lords of Waterdeep game from Wizards was surprisingly good.
