>>80971959the only ones i can think of that would be good on their own and arent just QoL mods are rftools and botania and industrialcraft 2 and some of the magic ones like thaumcraft
twilight forest would be pretty cool too and that would be decent as a standalone one i think
a lot of mods arent always updated for the latest version either so youd have to play a version which was a few patches too
