In my opinion, there is nothing wrong if you want to join and invest in a gaming project and that is valid because I am sure that you have done good research about this gaming project. and if you ask for an opinion then I will say not to invest in a game project because it is just a meme coin, and if you see it is a good and professional project then just invest a small amount.
insurrection isn't popular though. an investor will expect returns when they invest and it's best for them to just invest in well-known p2e projects. Immutable (IMX) GALA and Sandbox are the most popular as of now and although this is based on the ranking on CMC, i think the ranks are true.
time will tell for these games however. AXS was once profitable but looking at it this time, it seems the people who are still up to playing there are the ones who has no choice but to keep playing and waiting for the bull run i guess.
