I am working on a modpack to make the regular ic2 more hard mode style, but I am not using GT.
The ic2 config file gives great optioins on balancing the mod. You can decrease the output of all power generating blocks but... this makes the vanilla furnace pretty OP. Why would anyone burn 1 charcoal to smelt 4 dusts in an electric furnace, when a vanilla furnace will smelt 8 dusts for the same piece of charcoal?
My idea was to remove the vanilla furnace recipe and iron furnace recipe, but this makes smelting in the early game impossible. I can't find any config option for the iron furnace, does anyone know if there is a way to configure it? Or if there is a way to get around this?
Side note: has anyone else noticed in the IC2.ini file (config) that you can add custom recipes? Not as robuts as minetweaker, but still, pretty handy if you only wanted to add a few recipes.
If anyone has any suggestions on how to make ic2 more 'hard mode' I would love to hear them.
