The concept centers on a type of interactive digital entertainment where players possess the capacity to transform or upgrade entities, objects, or skills within the virtual environment. For example, a player might start with a basic character and, through gameplay and resource accumulation, evolve it into a more powerful and specialized form. This evolution process is often a core mechanic driving player progression and engagement.
The ability to fundamentally alter in-game elements provides a sense of agency and customization. This feature can lead to increased player investment and a deeper connection with their characters or assets. Historically, systems allowing modification have been a significant factor in the enduring popularity of many games, fostering a sense of ownership and allowing players to adapt to changing challenges and metas.
