Been meaning to post Gargantua’s “Research Facility”. It’s discussed here:
http://www.axisandallies.org/forums/index.php?topic=22164.30
I used it in conjunction with Der Kuenstler’s Tech tree and found it to be quite enjoyable. Basically each country starts with a Research Facility that produces 1 tech token per turn. The Facilities can be captured, bombed or destroyed depending on your preference.
Anyway a cool unit and one that will be added to “Global 40 HouseRules” which is discussed in the “Redesign” thread.
