something ive noticed in some games ive played.
resource mining upgrades: are they EVER worth it? i mean, they cost somewhere over 1000 credits after resource-to-credit conversions, and you get a 7% upgrade? wtf? thats going to take somewhere around, 20-30 minutes to payoff, and you can easily lose the game, or at least a planet or two(remember, the upgrade affects each extractor individually, so each planet you lose you lose the bonus for ALL the extractors you lost at that planet, thus further increasing pay off time), in that time where those resources wouldve saved your ass.
to me, it seems each resource upgrade you buy you're taking a huge leap into the darkness, where you're throwing most, if not all, your eggs in a basket hoping that you dont lose something.
opinons? suggestions? advice?
