This pack includes a lot of mods, so not every computer is able to handle it. But there are many technical mods including nuclear reactors which is the kind of setting the modpack has. But there are also some magical inspired mods in it, e.g. Thaumcraft or BloodMagic.
In order to play the this pack a minimum of 2GB RAM is needed. You can set the size of RAM, Java uses, in the TechnicLauncher options.
The hunger mechanics were turned into something harder which shouldbe a challenge for some of you. No that's not the only change in the configs, the ore spawning is slightly lower to present a feeling of having a lack of everything.
IMPORTANT:
This pack contains Fastcraft, by Player, enabled by default. Fastcraft enhances Minecraft with increased performance. Bug reports being made directly to Mod Authors should state Fastcraft is enabled.
If you enjoy the pack, give it a like. :-)
