Many good Minecraft mods

minecraft version 1.7.10
All the mods work well enough together, except galacticraft extraplanets causes conflics with biomes o' plenty.

You should probably delete either the extra planets file of galacticraft, or biomes o' plenty before creating a world, if you don't want some weird biome errors in your world.
But the mods do work together without crashing the game, so it can be played, just that there will be some wrong biomes on earth if using both mentioned mods at the same time.

I don't know if the issue can be fixed in the configs.

In any case you can just pick and choose any of these mods and play minecraft with them, you don't have to use all of them at once.
This is just some good mods I use.
