Got the Hotspring ending on my first playthrough and man, it was such a pain in the ass to make. It'll take you probably 3 months just to do the Dev Plan Peter gives you.
Once you get Rainbow on your end game weapons... the game is very easy. I barely even use attack items because my Meruru did more damage using attack than most of the items I had. Though to be honest, I never make items for battle... I let the Homs make them... rofl.
Anyways, was at max city level, max character level, max population. I didn't finish every Dev Plan. For some reason I didn't have a recipe for an item. (I forgot the name, but it was for the ruins where the Wyvern was.) The other Dev Plans I didn't finish were mostly just item usage related.
Sadly, I didn't get everyone's friendship level to 100 so I missed a few event trophies, everyone but Sterk, Gino and Gio were 100, Gino being the lowest because I never use him and he barely gives me quests D: I almost had Lolina's last event but... didn't have points to build her shop.
