The reward system and revenue model are among the principal differences between P2E and M2E.
Clearly, there are some differences between a P2E model and an M2E model. Both of them offer much more than virtual gaming, that is for certain.
Gaming is exciting, but relaxation and community engagement should remain central. Real gamers care more about the game and the graphics than about the revenue model. P2E is expected to become a mature concept within the gaming industry.
There is also a growing movement towards move-to-earn. For users who need the motivation to get enough exercise, a revenue model may be just the thing. However, the move-to-earn concept is still in its infancy, so we will have to wait and see what the future holds.
