Reverse Isekai Systm

The game system manages classes, worldbuilding, and assigns quests. It controls NPCs/monsters and other players but lacks personality or dialogue. Loot is tailored to player's class and achievements. Horror vibes at the start before players get stronger, with a grounded-in-reality feel despite the fantastical elements of the situation.

The real world transforms into a game-like environment where people choose fantasy classes, receive quests, and fight monsters for rewards. Classes range in strength, and players progress slowly with each level granting better stats and abilities. Some individuals focus on non-combat roles like farming or blacksmithing. This new reality brings out various emotions and motivations among people as they navigate forming factions, guilds, and engaging in international wars. Every person is playing whether they like it or not, everyone. Also random places can be transformed into dungeons, such as an underground parking garage, or an indoor mall. Horror vibes at the start, zombie apocolypse vibes in how people react to the situation. Basically the apocalypse in how society collapses.
