People, stop talking about "modern smartphones" and read exactly: It will be no native app. And this means either crap with a style of "war of two cities" or something pseudo-strategic for 2-3 hours. Surely nothing with the complexity of first civ. And I really hope I am wrong. And some words about playing Civ I on a smartphone. I managed to start it in a DOS simulator under WinMobile 2003 in 320x240 resolution and it worked fine. I could play with a stylus and use virtual keyboard and key mappings from the emulator. The processor speed was 200Mhz and it could emulate a 386 machine with about 10Mhz clock - more than enough for Civ I. AFAIK there is no working DOS Emulator for Android offering virtual keyboard. You need virtual keyboard and key mappings at least for units navigation - otherwise the game loses its charm.
