I don't think I've ever played RO, although I had a couple of friends who got really hooked years ago. I always thought it was a single game, I didn't know there had been multiple versions haha 😅.

Honestly I will never find a p2w system good, regardless of whether they have to profit financially, I think there are more ways to do it. The p2w no matter how minimal it is can frustrate many players, which translates into users quitting the game, in my opinion.
