Action manhwas with "System windows" and regression (or similar circumstances)

An ongoing collection of action manhwas. If you like MCs who have regressed, reincarnated, or something similar, as well as the classic, game-like status windows, dungeon crawlers, tower climbers, otherworldly portals,
and other similar vibe, action manhwas, you may want to take a look! I may also sneak in a few interesting MCs who undergo a sudden awakening, but still follow a system of sorts.

Manhwas are not added in any particular order. Feel free to reach out if you have suggestions!
