...Fighting a war on 3 fronts. But first, let me back up a bit. Starting a new game, I played with the sliders a bit. Small increase in research speed, small decrease in research cost, decent increase in tech multiplier. All in all, it LOOKED reasonable. Whoops.
Maybe 2 hours into the game, I'm in a slugging match with all 3 computer opponents. Our techs are fairly even. I got lead on them of maybe 2-3 levels, judging by the life of their ships compared to mine. Even then, my ships were swatting theirs like flies. I kept losing planets in a few systems because there really wasn't any feasible way to protect them with 300 ships drifted through the system. It wasn't as efficient as my fleets of jump-ships jumping from system to system extinquishing all life, but it was proving annoying. My tech levels were around 23 or so. This shows just HOW much a small change in the multipliers affects the game later (BTW, ramscoops were still useless). I decided to test build a ringworld. Instantly done. Nice. It was my new central shipyard. Lets pump out 1k scale ships instead of a mighty fleet of 100 scale. But wait! IDEA! Insta-building ringworlds because my techs are that awesome. Lets end this! Default Governor = Research world. Build on all: Ringworld. About a minute later, all my techs are pushing level 70 and still leveling up in seconds. *Cue evil laughter*
Naturally, having obscene tech levels, I went to redesign my ships. Then the game crashed. *Cue crying like a baby*. Moral of the story? Unless you want to break the game, DO NOT INCREASE THE MULTIPLIERS by .2. It sounds small...but it's friggin massive. ramscoops were still useless. .25 fuel cell would keep the ship fueled for roughly eternity.
