Gt... Hmmm enderIO, big reactors if you want nuke power without the "nukes" soul shard is kinda redundant if you have MFR's auto spawner on but thats me especially with extra utilities cursed earth I would not want to bother with dartcraft unless its for the lulz it gives time torches? Pft time controller? Pft makes the game silly... Especially once you start with dartcraft early game everything else is kinda eh... Mariculture too i would recommend if you like the water, mekanism if you like the xycraft tank feel with it's dynamic tanks and universal cables and is now fairly well documented but of course with GT in we would siggest also to edit the configs for TE and MFR to their respective dofficulty level these if were talking about tech mods else you can start with BevoLJ's pack in ATlauncher which revolves around GT's integration with reactor craft rotary craft MFR mekanism into the mix and ender IO already has carpenters blocks and chisel with it as well
