YouTube Simulator Z on Roblox is a tycoon-style simulator where you aim to become the top YouTuber by upgrading equipment, creating videos, and gaining millions of subscribers.
Record videos (click), edit them in your house (computer/editor), and create thumbnails in Photoshop to upload and gain subs/cash.
These are useful for faster grinding, though not strictly required for top-tier gameplay.
Find the editor item in the shop within your "mother's house" to help automate processes.
