I lean more towards Total Annihilation/Supp Comm on Steroids. SuppComm 1 anyway. I hope Ashes doesnt decide to do SuppComm 2. While the game play was similar, you had to research the same techs every scenario. Why? because maybe the radiation destroyed your memory. Till you were lucky to remember your name? I think it was to artificially increase playtime with less content. There is never any reason you have to relearn everything from one mission to the next. SC Forged Alliance was an almost perfect example of how to do tech trees. Then they regressed for SC 2. Please do not do that in Ashes..
