I have been playing singleplayer (until i am whitelisted) to get used to the mods and i have been literally watching any tutorials updated to the version in game. The tutorials are really helpful. Many i watch are from Direwolf20, he has good tutorials.
I honestly feel like i would MISS modpacks if i were to play Vanilla singleplayer now XP.
i cannot wait, i want to get started so badly =D.
