1/2 Prince

if it's something like gaming world, try:

Real Account (they are in virtual world, but still playing games or such in order to survive. Pretty much like SAO without combat element)

Real Account II (the sequel of Real Account)

Online - The Comic

Rei - Kage Miko (this one based on horror game Fatal Frame, but not quite in gaming world)

I think line webtoons has few in this genre, you should check it if you have time!

honorable mention: I think most of us already read Akatsuki no Yona, it has rpg feel like Suikoden. You should read it if you have not~

The gamer(webtoon) its about a dude that lives in the normal world as an MMORPG character ✧✧✧✧✧
