You can play this pack just like any other survival modpack, it's got a lot of Tinker's stuff and also Thermal Expansion for your tech-needs.
The only difference to vanilla minecraft is that you should craft tinkers tools and weapons as soon as you can.
Because of TAIGA there are a ton of fun materials to play around with, each with their own traits and properties, so you can create some powerful combos.
Well, do as you want, battle each other, call in armies of mobs with commands, whatever!
If you experience any crashes, tell me about it.
Have Fun!
Disclaimer:
This is not "my" modpack from the ground up, I just added some more mods and addons to the Tinker's Modpack so it'd be more fun.
I made this just to play with a few friends, do not expect absolutely perfect stability out of this.
