i've been waiting quite some time to give this update
techs are sketched out and plotted. of course, nothing set in stone. but this was a big hurdle, designing it from scratch. and as always, i wait until the end of the design phase to plot it all out b/c no sense in plotting if i don't have all the plots
iow, i need all the 'stuff' in the editor, units, buildings etc. now that they're pretty much finalized, i could draft the tree. please excuse my chicken scratch
era1 - 1942 - 35 total game turns
notes: black outline on the tech box means that all civs can research it. red means Japan only. blue means Allies only, and the neon green highlighter hue is the US nuke line. 1st era is only 35 turns. each game turn equals one (1) week and the scenario starts first week of may 1942. iow, not a full calendar year.
era2 - 1943 - 52 total game turns
notes: the split boxes you see on the sketch mean that those techs will have the same x/y coordinates and if it says 'Japan Only' then this means that they will require the 'Japan' tech to research. iow, they will not appear on the tree for the allied civs, only Japan. Kly convinced me to do separate trees for the allies and japan. more work for me but not outlandish...i did have to do some maneuvering though.
era3 - 1944 - 52 total game turns
notes: the biggest era in terms of total techs. will probably set min/max science rate at 2 or 3 (prob 3) min and 30 max. will tier the prices of techs based off of the era (era 1 techs cheap, era2 less cheap, era3 more, and era4 the most). think AoI. this is how it's set up for that old beauty
it worked well and i'm gonna use that foundation for this scenario.
era4 - 1945+ - 52+ total game turns
notes: yes, i could probably add more to this era. but i'll leave it as is for now. always room to grow and that's ok. but for now, it is what it is and it's not so bad imo
in a nutshell, japan and the allies have separate sea unit tech lines. this was for you, Kly
however, they share the ground lines (nearly identical amount of units unlocked) and also the air lines (very close as well). so this is why i kept the ground and air as one line (rather than create 2 like for the sea units). there are some air lines (and the ground line for era4 irrc) where i added on civ specific techs at the very end of the line for that era. took a little creativity to squeeze these in but i think this will work.
