when I play I don't feel like theres enough time to use units before they are obsoleted by newer technologies. The game basically flies through without the chance to enjoy any one period of time. I tried playing on marathon to combat this but that also makes it take ten times longer to create units so it ends up being the same thing pretty much. Trade brokerage off didn't really help either. My latest idea was to do accelerated production with marathon only to notice that wasn't an option in the game anymore. Are there any mods that solve this problem?
