Well. Since we want to talk about players going beyond even level 60, and then there's someone who wants to talk about going beyond.
I'm going to go ahead, and talk about a MMORPG named Black Desert Online. Black Desert Online have no known caps, as of this present day. Since there is only soft-cap, after soft-cap. Nobody had realized the highest level there is, saves for tremedous amount of grind that will to come. There, already existed players over in the game's founding country Korea, that reached level 64 after nearly years of grinding.
The soft-cap beings, currently, at 56. So you starts to try, and walk through all that mud. Trying to get to level 60, where remainder of the skills are left. So you can utilize them. The issue is, it's very grindy. So it'll take tremendous amount of fighting, farming, and even combating. It takes around a year, and a half of constant to go from level 56 to 62. Then it will take a year to get to 63, and already will it take two years to get to 64.
The grind is large, and it's not very brief slope. It's expanding, dangerously tall mountain that pierces even beyond the time, and fabric.
Hell, someone sent an email to GM asking how many generations they had to do just to get to 'assumed' level cap. They said, generations after generations. Meaning that it'll take hundred of years to get to level hundred at that point.
