For example, telekinesis can be limited in time and size, and if the GM wants to really "ground" the game, they can make it quite weak, but occasionally useful.

Telekinesis hasn't even been proven theoretically, let alone its practical application, so how do you envision it working?

Besides, people signed up for a specific setting; it was initially stated that it would be about the present day, without any fantasy elements. Ara and I would have preferred fantasy, but we're just sitting here and not complaining because the rules are the same for everyone.

By the way, Koschei's immortality is presented as "vague rumors," meaning that, in reality, the GM will decide how to interpret it (and he has already decided :smile04:).

P.S. list of promising technologies, just in case. Although, even if each country adopts one, there will be problems with balance and the "equivalence" of these technologies.
