'--- THIS WAS EDITTED AFTER FINISHING THE MODPACK ---

After finishing the pack, I can't say that I would recommend this to friends. This modpack, while having its pros, and definitely some interesting mods to get into in the mid-game, the end-game grind using ProjectE and going up flower tiers after completing every single quest, makes this modpack feel shallow. The end-game boss is not really a threat, the mods you explore and end up using are useless in the end-game and even if you wanted to adventure out into the world with this new found power, it's made boring with the lack of proper terrain generation in any of the dimensions (maybe excluding the End).
Yes, the premise is interesting, but there is no story to continue that feeling of discovery, but rather a checklist to dot, and a slow, monotonous and grindy end-game, with nothing to show but a "Final Star" that doesn't really have a purpose other than to flex to yourself with in a singleplayer world. There's no real exciting multiplayer elements here either, so forget doing or exploring anything really interesting past the first 2 ages. If I could give the author of the modpack any actionable changes to be made, it would to rethink how terrain generation is done, and to give the end-game purpose, other than a grindy wait game for EMC to generate.
For now, find another modpack that does progression better until this one is further updated, you'll be disappointed.
