Lost Odyssey is the easiest game for that achievement, zero grind involved. Scenester is just lazy.
I would rank them as
1. Blue Dragon (missable items for the easiest things, required grinding to Level 99 - unrelated to treasures but in general)
2. IU (missable items, crafting, grind involved to defeat final optional boss for 1 item)
3. FF13 (not much grind involved to reach max, just lots of unnecessary farming for Ingots and Traps, nothing missable unless you really tried)
4. LO (zero grind, nothing missable)
Vesperia had one too but I dont think it was that bad, least I can remember. If I had to place it, it would go between IU and FF13
