Exactly that. If you haven't played a 1.6.x pack before, Crash Landing is definitely NOT the place to start. It will frustrate you to no end.
Sorry, this a hardcore pack. It isn't unreasonable to expect that people have some idea what they are doing in this case. And you are expected to die a few times, although I do offer an easy quest option that should make life less difficult.
I don't expect this pack to be fun for everyone, and it is perfectly fine if you don't like it. It is designed to offer challenges unique, or as unique as I could get, to modded Minecraft. I'm aware this won't be everyone's thing.
