# 3.4.2 Nava GameHUB

**GameHUB is a full-fledged scalable node (hub) with gamefi products within the NAVA ecosystem.**
\
**GameHUB includes a gaming ecosystem with internal game currency, game seasons, and leaderboards.**

*These are more complex and interesting games created using the Unity engine. Each season of games includes new games and updates to old ones.*
\
*GameHUB has a concept called Community Energy (CE): the more players play, engage, and invite friends, the higher the community energy (CE) indicator.*

At the end of the season, CE must be maintained at a certain level, and then the top 100 places (the number may be changed) on the leaderboard will receive a reward. Otherwise, if CE is below a certain level, only the top 3 places on the leaderboard will receive a reward.

In this way, the community of players is motivated to collectively maintain activity.

Each game season marks a certain feature or update in the NAVA ecosystem. Thus, seasons can be timed to coincide with, for example, the launch of a new product or a new feature in a product (such as the launch of a chat feature).

Players also have an achievement system and an avatar system. These systems overlap with the systems from Lottery p 3.4.3.

<p align="center">
<br><mark style="color:blue;">The difference between GameHUB and Lottery is that GameHUB is a larger and more scalable system designed for PvP modes and the addition of more complex games, as well as expansion into the metaverse (optional). You can find more details in a separate product presentation.</mark></p>
