# Core Game Loop
Players' assets move between the economic and combat systems in different ways, with resources serving as a crucial link. Resources can be obtained directly from both systems or purchased with real money within the economic system. Players have various options for utilizing resources. They can use resources to incentivize group or community formation, thereby promoting the growth and generating more resources. At the same time, resources can also be utilized to enhance the player's combat abilities, contributing to the effectiveness of the entire combat system. Additionally, players have the option to trade resources within the economic system to acquire cash.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://pepa-labs.gitbook.io/pepa-arcade-1/gameplay/core-game-loop.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
