Pre-registering doesn’t entail much. Head to theofficial site(or follow a link on itsEpic Store Page) and you can press a button to sign-up for a HoYoverse account, or sign-in with an existing one, and I guess express your interest in playing the game by doing so. ZZZ will be free-to-play when it launches.
Collectively, the number of pre-registered players will unlock in-game rewards for players, with the top reward requiring 40 million pre-registered players. Which sounds high, until you consider that at the time of writing there are already over 32 million.
I’m genuinely excited forZenless Zone Zero, because I liked Genshin for the 15 hours I played it, and more of that flashy, multi-character action-RPG combat, this time with some Jet Set pizazz, seems like it would be a good time. My interest will rapidly dissipate, however, if ZZZ’s main missions are gated behind an in-game currency as they were during a beta late last year. Genshin avoided such mobile monetisation strategies and I’m still hoping ZZZ will do the same.
