Can anyone give me a good reason or strategy to buy A-era factories ?
After a few games I've noticed I almost never had any use for them.
Their spyrium/points ratio is not as much of a problem as worker/points ratio. They are just not worth spending a worker, especialy at the beginning when you don't have many of them.
What worked for me best was to ignore them completely and focus on everyting else, until I had stockpile of spyrium and could buy B or C-era factory and pump spyrium into it as fast as possible.
Even using it for discount doesn't seem to be worth it.
Am I missing something ?
Hi. They are worth it, sure.
a) As mentioned, you can get to 8 VP quite fast, especially if you happen to pick up the Engineering Patent. You just need 2-3 activations.
b) If you buy a £2 factory and upgrade it, you've just earned a buck.
