Firaxis do not have the rights to Master of Magic or Master of Orion. As a result, their Civ Chronicles version of Civ2 is missing the scenarios based on MoM and MoO. This problem cannot be solved in the foreseeable future.
Even with the MGE's two most obvious bugs fixed (the AI, and misplaced portrait of a certain AI leader in the DLL), the MGE do not fully replace the original Civ2, because it does not have the original Civ2's Adobe Director-based civilopedia. That civilopedia is a large part of Civ2's aesthetics.
A good release of Civ2 would have to contain all three versions: the original Win3x version with both scenario discs, MGE, and Test of Time. And that's not counting the issue with the scenario theme tracks added since the scenario discs - you wouldn't want to hear them when playing a vanilla Civ2 game, but wouldn't want to miss them when starting their respective scenarios.
Similary, Civ1 essentially has three "canonical" (developed by Microprose) versions: the DOS original (with four patches making a few changes), the Mac/Win3x version with new graphics, and CivNet, which has mutliplayer and CD audio music.
