So we could use 4 deathfish and not 4 different kinds of fish? And what, 4 money bag? I just did some checking with my immortal dynasty. They have complete collections of everything available to me in Sunset Valley. Top 4 gems total 12,462, metals 3802 (if these didn't have to be all different metals it could be much higher), butterflies only 1,868 and sorry there's no way to catch 4 rainbows in medium lifespan, beetles 2,043. I didn't save the space rocks - they're not pretty. A multi-generation 16k collection would bring more variety to the collections and bring back the group effort aspect.
