"Maybe you can use Achievements as a check list, lots of mods (e.g. AE2, Botania, Buildcraft, Twilight Forest) have its own achievements, try to follow that to get more idea. Or like /u/hilburn suggested play a HQM pack. Wanderlust Reloaded (FTB 3rd party modpack) have very good quality HQM quests introduce you to major mods and reward your progression" - number5
