Thanks for this:

With regard to finance, does this include the topic of crypto games?

Crypto games are fine since they will touch the financial part where others can benefit from.

Can the text of freewrite messages be used (as a skill and skill)?

Writing itself is a skill. So, freewriting is fine but the topic should have meanings.

Is it difficult to imagine a practical application in the category of product evolution (could it be the evolution of a particular crypto game or crypto project)?

This is the easiest. You are right. The evolution of the crypto project is fine. You can talk about the first version of an application up to the current version. You can write about the first type of computer to the current generation. It is a wide topic.
