Update 2: I got banned on VRChat discord for posting VirusTotal results of analysing the Easy Anti Cheat executables that were added to the base game. Tried to rise end user awareness, VRC Dedelopers censored it.

Don't take my word for it - analyse the files yourself. If you dont like or trust Virus Total - analyse them in a sandbox of your choice - cucko, any.run, malice or any other. EAC is malware no matter how you glorify it.

Updated review: VRChat Developers just posted an announcement that they will be installing malware (Easy Anti-Cheat) along the game client suposedely to improve the games security. Any anti-cheat ran client side does not improve security and since the service runs at evlevated privileges (System - above administrator access privileges) it poses a security threat to end users while pretending to secure the server from end users.
The truth is that malicious users will have no issues disabling such a feature while legitimate users will be exposed.
As such I don't recommend VRChat - at least until developers come to their sences and fix the securty flaws properly.

Old (positive) review: Since this is not really a game but a social platform, i't cant be graded as a game.
Everything is VRChat is pretty much user created content. A lot of wonderfult worlds to explore, minigames, hangouts, clubs. perfect place for a full featured Virtual Reality Experience where you can become whatever (avatar) in pretty much any setting you wish - modern, fantasy, science fiction - you name it.
Beginings are slow, public worlds can scare some people away, but exploring the rabbithole opens a lot of new possibiities, specially if you invest time to learn some basics of blender an unity to edit or create your own content that you can use inside of VRChat afterwards.
Definitely a must try for people who would like to experince the closest possible thing to a Star Trek Holo Deck.
