Nah it's a Isometric RPG as far as I am concerned. Using the broad term of ARPG means anything from a FPS, TPS, Roguelite, Isometric, Arena Battler, Character Action Game, Spectacle Fighter, Beat em up, WRPG, JRPG, Twin Stick Shooter, and much more all apply if they have RPG elements and a real time action system at play.
It's why I found it odd the thread was all "DISCUSS ARPGS" and it was all "Isometric games" instead.
Like I previously stated best Diablo clone is probably Grim Dawn.
I'd like some new Diablo Clones to try but I've pretty much played all the prominent ones when they were in Early Access like PoE, Last Epoch, Wolcen, Warhammer Inquisitor and then much older games like Sacred Gold, Titan Quest, Torchlight, Older Ys games, Xanadu Next, Darkstone, Baldur's Gate Dark Alliance 1/2 and if they ever port it Champions of Norrath.
Dunno if I will revisit it but Hellgate London is always a guilty pleasure.
