So what are the fully fledged tech mods and magic mods?
For tech the ones (off the top of my head):
- ThermEx
- Engineers Toolbox
- Ender IO
- IC2
- RoC (rotarycraft)
- Gregtech
- Hydraulicraft (from what I've heard)
- Mekanism
In its current form I'd discount GregTech. Until he leaves beta with the no-IC2-required version it's still an addon.
