From a game point of view, do you think its worth it to play?

It has a certain charm about it, the gameplay is very fluid and it doesn't demand a huge PC to play. Mine is crap, but I had to get some more RAM for it to work well.

I want to play fun games and rather than just crypto games :D

My discontentment with Splinterlands took me here. Since then, I have barely touched SPL. That is far from fun, more stressful.

Do I have to buy any charater as they sugguest from Magic Eden?

Yes, or Okx. I thought they were a mirror, but it seems not. If you jump, make sure you research your skills first, as they are not changeable.
