LOL then you picked THE WRONG game my friend.. The is no "point" of minecraft its a "Sandbox" game.. THe point is to do whatever you want in the game and have fun doing it.. Whats fun for me in ftb is to challenge myself to build more complicated contraptions and I'm also really getting into learning Lua from using computercraft.
of course it is a sandbox, but there are stuff that isnt pointless, like beacons, or portal guns, or defeating the dragon.
In vanilla I have no problem on keeping playing, but FTB simply doesn't have enough end game stuff (mention me at least 3 items that you consider endgame outside IC2, good luck)
