If you're just getting into rhythm games, I'd recommend starting with titles that have a slower learning curve like Beat Saber, Rhythm Heaven, or even mobile games like Cytus. They help build timing and coordination without being overwhelming.
Interestingly, I’ve seen some crossover between rhythm mechanics and other genres too. For example, in avatar world (a game that’s more exploration-focused), certain mini-games or interactive scenes have rhythm-based elements—especially when interacting with music or dance-related items. It’s not a traditional rhythm game, but it can be a fun, casual way for younger players or beginners to get used to rhythm-based gameplay in a low-pressure environment.
