BoobyLegends review
BoobyLegends is a browser card game with seasonal collections. Its FAQ describes how new cards open media and what happens to a collection after the season changes.
What you keep at the end of a season
The FAQ says cards from the ending season are withdrawn from the market and returned to their owners. Past-season cards stop appearing in standard spins, but can still come from All-Time boosters. Rankings for the old season stop moving. The September 9, 2026 patch notes introduced an automatically renewing Golden Pass option.

Collecting cards or unlocking one quest
BoobyLegends ties its media access to individual cards. Qwinky lists credit packs for specific filmed quests. If you already know which story you want, an individual unlock gives you a more direct route. The seasonal rules matter more when building a collection is part of the appeal.
Anabel’s take
I'd start BoobyLegends for the collecting. I'd choose an active season where I could see what I wanted to work towards, knowing older cards follow a different route.
