The short answer is no, MacBooks are not good for gaming. While MacBooks are recognized for numerous advantages, they're not commonly the first choice for avid gamers.
The 14-inch MacBook Pro with M3 Pro chip is a good option for gamers. We suggest that if your budget runs to it you should opt for the mid-range model that comes with 1TB SSD, 12-core CPU, and 18-core GPU (forR$2,399/2,499). That way you avoid the slower SSD of the entry-level model, and get the extra GPU cores.
