FTB 4 Life!
In all seriousness, I'd like to join the new server when it rolls out, but I literally have zero imagination when it comes to building shit. I load up vanilla and just sort of hollow out a mountain for my base every time because it is so easy to start that way...and then I get bored. I load up FTB and I do the same thing, but then start getting into power generation, then into sorting, then into quarrying...and then I get bored.
Several servers ago I started on a floating city concept that I really liked, but it would have literally taken me months to build, and I've done enough generic building in my Minecraft life that I get bored with that too. I need some sort of inspiration, but I honestly have no idea. I get distracted with mining and other stuff in vanilla because building gets boring, so even if I have an idea I get tired of it. I'm trying to come up with an idea before I even log in so that I'll have a purpose right from the get go. Hopefully I'll come up with something soon, I've been itching to Minecraft again.
