Would you be willing to answer a few brief questions about PlayStation Forums?
I'm at approximately level 30. I consider that high
Generally I see people talking above high level - anyone with triple digits as their "level".
Level 100 and above considered as high level for me. (Even though I'm lvl 170 ish)
But it can also be if you're level 100~200, level 400 and above are high levels for you.
I have friends who are level 400, I believe level 999 will be their high level.
