this game has rock-paper-scissors bro Cr > LF BC > Cr LF > BC
and rock-paper-scissors-lizard-spock LF > BC > Cr > LF > De > RIP > everything else
Light Fighters = cheapest fodder = good Heavy Fighters = expensive fodder = bad Cruisers > LF (due to rapid fire) = good BattleShips = very expensive fodder = bad BC > Cr & BS (due to rapid fire) = good
Destroyers are for killing Death Stars (like 99% of their job) Bombers are bad (only good for killing defenses, which you should use Death Stars for) Death Stars are for killing turtles and making your fleet saves take longer (good thing)
tl;dr HF, BS, Bo = bad LF, Cr, BC = good De, RIP = situational
Makes sense... I still haven't gone for gravitation tech so no death stars for me any time soon lol... If I remember correctly I'd need to build an additional 7,000 solar sats which sounds terrible right now
stockpile the "reduce shipyard contract" items (trader > import/export and buy an item every 24 hours) and get your nanites high enough to build 1 second satellites.
then stockpile enough resources to build them all at once (keep the res split across planets and only pile it all together when you are ready.) and FLEET/RES SAVE THAT STUFF UNTIL YOU ARE READY!!!!
then you can queue them all and just spam reduce time items until it reaches 0. (make sure you have enough items before you queue the satellites)
then do your 1 second graviton research (if you forget this, you will cry)
then go to trader > scrap merchant and convert your extra 7,000 satellites back into resources. you don't need dark matter, just take whatever ratio he gives you. it's that or get crashed & lose it all to someone bigger than you while you're offline.
