Glitches & Anomalies: Embrace the platform's inherent instability. Random teleportations, temporary asset swaps, unexpected crashes, and bizarre physics can be integrated into the narrative. Players could encounter "memory echoes" – fragments of previous OpenSimulator instances bleeding into the current one.

User-Generated Content: Encourage players to contribute to the world. Perhaps they can build structures, create quests, or even design new creatures. This fosters a sense of ownership and makes the experience truly collaborative.

Avatar Abilities: Consider how player avatars can be integrated into the gameplay. Maybe certain avatars have unique abilities or vulnerabilities.

Location Based Gameplay: Make use of the virtual geography. Different regions could have unique rules, challenges, or resources.

Voice & Text Chat: Leverage the platform's communication tools to create a dynamic and interactive experience.
