Originally I had planned for only Communsim to be the required tech, but it didnt seem ot want to work unitl i also made Steam Power as another required tech, which works and seems to me to kinda fit in with the whole industrial feel, though I may change that to another tech as I play with it.
I'm sure that replacing techs is as much if not bigger hassle as creating new ones, and I'd be willing to have a look at it on my end and experiment. Just gotta come up with a lot of new concepts.
I still want my Lubyanka wonder, and there could be many others when I have a look through what literature i do have here (not being Russian, just a Russophile I have to rely on secondary sources for my idea) I wonder what a Brest Fortress or a Krondstadt wonder could do for one's military?
