Are there any mods that keeps production for buildings/units the same but increases the amount of science needed to research technologies? I feel like all the units become obsolete in like 20-30 turns and have to keep upgrading...I like having the same units for long time so feels like each era the wars last long time with same units. Are there any mods like that for VP? Feels like once you hit industrial research cost for each tech decreases significantly...I'm looking for opposite where it takes a LOT longer to research each tech. Slower Science Longer Eras https://steamcommunity.com/sharedfiles/filedetails/?id=320492804 ^ Tried using this one but after classical era I just blow by every tech super fast where units become obsolete in ~20 turns and need to keep upgrading even before a wars are finished. Looking for a mod where it takes super long (marathon) to research each tech but building units/buildings remains same as standard/epic speed.
