Another important note is how Sid Meier was involved with the newest XCOM games as a co-designer and mentor to Jake Solomon. The marketing and promo for the games are centered a lot around Solomon as the figurehead for the game to the point that people commonly complain about the numerous (not game-breaking normally) bugs with "Jake, fix your game." Nobody really ever had that attitude with the Alpha Centauri, Civilization, etc. games to my memory.
