I don't remember ever having to collect Forget-You-Nots, but I know I was able to find the collectables I was missing by going to the places I was told they would appear. You might have to make a couple trips there I suppose, but I didn't find the "rare" collectibles to be too challenging. Keep trying (time of day counts too) and I'd imagine it shouldn't take you that long before you get them.
As for your issue with the area you are in, I thought thatbut I do agree that more types of Mechon (rather than just new nonsensical names for old models) would have been nice. I liked that area overall though, and recycled enemies (albeit with different names and colour schemes) was a trope that this game unfortunately didn't avoid all the time. You do still havethe atmosphere of Mechonis was quite different from that of Bionis, which made it interesting, but hopefully you can still enjoy them.a couple areas to go through that are filled with Mechon
This is the first time I've had a hard time finding something this badly. I think I'm just getting very unlucky.
And like I said, I'm still enjoying this, definitely. Just relative to the other parts of the game, this feels like a slog, mainly cuz the area is just so big and it doesn't have quite the enemy variety of previous areas. I spent a good 3 hours playing today and while I spent time doing other stuff, I did make an effort to continue on with the story a bit and am still in the same area. Affinity between members is going up quick with all the fighting, though!
