Idea.
Add different types of insect collections:
- the current 6 types - "Small Bug Collection"
- 12 - "Medium Bug Collection"
- 18 - "? Bug Collection"
- 24 - "Large Bug Collection"
- all types (29-30?) - "Full Bug Collection".
*The names are approximate.
Reason. The curiosity is called a collection. But you can only make it from 6 different ones out of 29 (?) - this is more of a beginner's collection. And to create it, 6 different ones of the best quality are used. Collections of varying completeness will encourage people to collect all types of insects.
At the same time, this curiosity is the most popular. Finding 6 insects is not difficult. Adding new collections, reducing the points for each unique one from, say, 2000 to 1500 (or less), will help balance it. At the same time, by increasing the number of possible unique ones, collecting insects for curiosity items will remain profitable.
