the pet catalog here is enormous and thats the whole appeal for me. collect every pet, then the neon (four of a kind) and mega neon grind gives each one a real completion path instead of own-it-and-done. the tasks loop is shallow, wont pretend otherwise, and the trade economy has some pay pressure baked in. but purely as a collection game the breadth is huge, and aging pets from newborn to full grown then fusing to neon is a legit long haul goal. solid 4 for completion value, would honestly be a 3 if the catalog was smaller.
