RDAMC

This pack includes:
Lost cities : which adds scattered abandoned cities around the world begging to be explored, (configs are tweaked and this pack is intended to run Lost cities: Rare cities)

Ancient Warfare : which adds everything medieval you could want. from siege engines to NPCs you can assign to do almost anything
AW also adds NPC factions and military & civilian outposts into worldgen

Simply Jetpacks : to help you explore the world

for tech we have the Thermals as the base tech mod, with mekanism and Nuclearcraft for power gen.

RF tools lets you build you own dimensions, as well as adding cheap auto-crafters and bulk storage means.

there is many more mods like Draconic Evolution, Applied Energistics, and Mystical Agriculture just to name a few.

in the end the goal of this pack is just to have fun, whether you are new to modded minecraft or a mod veteran, technophile or a wizard, you will have fun. a lot of configs and mods exist just to make things a little easier, extra hearts come often, you can grow trees in small pots indoors, and sandwiches can replace all food you will ever need

however there is things like the naturally hostile Ancient warfare dungeons, and Zombie Awareness, as what good is all that firepower without a use?
