Ew, Gregtech and Reika mods.
Diyo, try building cities with your extra resources, perhaps a floating airship with potion shops and weapon stores.
Really the problem with tech mods (save for ThermExpac really) is they give you too much resources because their recipes are usually expensive as hell. Why do they do this? because Minecrafters seem to think tedium = difficulty. Hence BTW and GT5. These two mods are only popular because it fools people into think they're hardcore players when they're just GUI fanatics.
How to solve this? Don't play tech mods, or play better ones like Resonant Induction (sadly it's a Calclavia mod, so it's nigh unplayable). Too many tech mod rely on psuedo-industrial and modern tech. People like us just need to wait for a mod that uses mechanical power, gears, and other actually interesting stuff.
You are so wrong, I dont even know where to begin. People dont use gregtech because they think they are "hardcore". They use it to extend the life of their game. And it works. And you think Resonant Induction (when it finally works) wont be tedious?
Half the fun is combining mods together to come up with something awesome. For example, a flux infused jetpack, a dark steel helm, and boots of the traveler enchanted with haste1 and slowfall is a truly awesome set of armor with flight, enhanced speed, night vision, step assist and a glide down instead of falling. Thats five different mods you would need infrastructure for. EnderIO, TE, Simply Jetpacks, Thaumcraft, thaumic tinkerer.
