This is a good thing, as long as a few things are in place for the official release:
1) The manufacturing cost of the Highest buildable tech is the sum of its cost minus the cost of its predecessors:
Example:
[Tech 3 Factory cost] = [Tech 3 Factory cost] - ( [Tech 2 Factory cost] + [Tech 1 Factory cost] )
2) If the player chooses to build a Factory, and has the capabilities of building the Tech 3 version in 1 turn, it should still only take 1 turn
3) IMPORTANT: If I want to build a factory (and I cannot do so in 1 turn), the entire factory should upgrade FIRST in cue...
Example:
---------------------------------------------------------------------------------------------------------------------
Turn 1:
Cue: 1) [TECH 1 FACTORY] = (Have techs for Tech 3 factory)
2) [TECH 1 FARM]
Turn 1 completes: Tech 1 Factory is built (if player has production in 1 turn to complete Tech 2, then Tech 2 factory is built)
---------------------------------------------------------------------------------------------------------------------
Turn 2:
Cue: 1) [TECH 2 FACORY] = (Overflow production from turn one goes here)
2) [TECH 1 FARM]
Turn 2 completes: Tech 2 Factory is built
---------------------------------------------------------------------------------------------------------------------
Turn 3:
Cue: 1) [TECH 3 FACTORY] = (Overflow production from turn two goes here)
2) TECH 1 FARM]
Turn 3 completes: Tech 3 Factory is built
---------------------------------------------------------------------------------------------------------------------
Turn 4:
Cue: 1) [TECH 1 FARM] = (Overflow production from turn three goes here)
