first I start with saying that end game for me is have infinite resources and nothing to do with them.
I started a DW20 world (without IC2, xycraft, ee, factorization, and reliquary) and after like 3 days I have infinite biomass, charcoal, energy, steam, a quarry at max speed and a crapload of resources, now I don't have anything to do with them (that has a point, I don't do stuff that is pointless) and I feel I reached end game, I killed the enderdragon the first day, finished thaumcraft in the second, I have 25 nether stars, a 5 beacon pyramid, and really nothing to do.
now with ic2 there is no difference, as soon as I have a lot of resources that are just sitting in barrels, I don't need anything else, since thats my endgame. And gregtech just makes me to get to end game in like a week instead of 3 days.
neither doing a quarry frame, galardron drill, forestry farm is useful, is just pointless, waste 10% of resources to make something that gives you 200% of what you have.
or do pointless stuff, like have the base in a frame ship, or doing trains sorting systems, that is just pointless, and I dont do stuff that is pointless.
any ideas?
