FromSoftware's Elden Ring might be the first game developed by the Japanese studio to feature a proper anti-cheat solution on PC, namely Easy Anti-Cheat. The report comes from Reddit user hzy980512, who was the first to skim through the newly published Elden Ring third-party EULA (End User License Agreement) and noticed the following paragraph at the very bottom.

24. THIRD PARTY SOFTWARE.

a) EasyAntiCheat. BANDAI NAMCO is using EasyAntiCheat anti-cheat service (“EAC”), which is operated by a third-party service provider. EAC has a client software that is integrated into the Game. When you start the Game, the EAC client software will automatically load and install its latest version to the Hardware. EAC will monitor the Hardware, analyze the Game binaries and scan Hardware memory for the purpose of detecting and preventing cheating in the Game (“Purpose”). For the Purpose, EAC stores information regarding cheating methods used in the Game (“Cheat Data”).
