For the first time i've researched the entire tech tree, every other game i've played i won before this happened, but in my current game i'm going for a 20K city victory and it's coming down to the wire, so the game is going well into the 21st century.
I was surprised when i suddenly realized i was researching "Future Tech 1," and was excited about it, having never heard of such a thing before. But once i got it, it didn't seem to do anything for me. No new units, buildings, options etc. It also seems i can't trade it with other civilizations.
So, what exactly IS future tech? Does it do anything or is it just something added in so it doesn't look like the tech tree ends? How many future techs are there?
Thanks in advance to anyone who can fill me in.
