For all the people who are saying this mod is OP...
1. Personally, i like having the ability to use options that arent end of game. makes it a bit more enjoyable.
2. remember that this mod IS in beta and that balance isnt the biggest priority right now.
If something is "in beta" and "not balanced yet" I don't see why it should be included into a "production" pack.
As it stands Dartcraft completely breaks early power generation. Very early game the "best" engines used to be hobbyist engines at 1.6MJ/t each. Now it's Force engines that give 8MJ/t, require less expensive components, and don't need an infrastructure to create the fuel (unlike charcoal) because it's abundant.
You can now just plop down 3 force engines and an aq accumulator, have a quarry run at 24MJ/t (great speed) and basically power itself with the force gems it digs up. It completely removes the challenge of getting a decent power supply early game.
I think it's great to add cool mods to a pack but if a mod author just adds stuff that is MUCH cheaper just to get people use their mod (seriously, what else is the force engine there for? The mod doesn't even really use MJ so why does it add an engine? Yes, to get people to use the mod. If all modders would do this we'd end up being able to build anything from dirt and cobble in a year or so.
