Here are some tips early game (T1 or something):
2. This might work, but when I use an oxygen bubble distributor for when I "ignite" a heart of star, it gives a depleted nether star and any kind of star with power, which means ultimate stars all for the price of charging a star and using crushed diamond, crushed gold, etc. to make another Heart of Star.
Crushers require Desh and you can only use one star at a time for power
3. It takes 86 diamonds (1 stack and 22 diamonds) to make one Polytool. You can use leftover decomposed diamonds to make 4 stacks of carbon for stirling generators.
Who has 86 Diamonds early game?
4. If you don't want to spend the time making nether stars for gravity armor,...
How are you making Nether Stars early game? Fission/Fusion Chambers are not T1.
5. If you get the quest where you have to choose between 2 spawners, the first one is a blaze spawner and the second one is and Enderman spawner. Hint: Choose the Enderman Spawner and use MineChem for fuel/power.
6. Instead of a bunch of iron and diamond chests, you can use the Storehouse from QuantumFlux. It's kind of like the ME systems but without the crafting thing and the need for power.
Bunch of Iron/Diamonds in early game?
8. Use the nuclear furnace. It can burn 64 items in like 10 seconds using 1 uranium or thorium. The uranium and thorium can be obtained from sieving Pluto rock and you can use crushed uranium/thorium for fuel instead.
How'd you get to Pluto?
9. You can use a player interface to take spare empty oxygen tanks from your inventory (middle side) and put air into it and send it back into your inventory. I used EIO item conduits to match the MEI (I think) data so it'll only take empty oxygen tanks and send back full oxygen tanks.
