Titan Quest is a hack-n-slash action-RPG based on ancient Greek, Egyptian, and Chinese mythology. It seemed to fly under the radar back in 2006, and yet somehow, for some reason, publisher THQ decided to release a massive free update for it 10 years later in 2016. Dubbed the "Anniversary Edition," this new version is a complete overhaul of the original game with performance tweaks, improved functionality, new features, and better balancing while also throwing in the Immortal Throne expansion. The core gameplay follows the traditions of Diablo, where you work your way through a series of levels fighting enemies, collecting randomized loot, and investing points in skill trees when you level up, all in an overhead axonometric view with a mouse-driven interface and real-time combat.
Action-RPGs aren't usually my cup of tea. I played some of the original Titan Quest back in 2007 (the "Gold Edition" box is still sitting on my shelf) as well as a few others in the genre (Diablo, Diablo 3, Dungeon Siege, Dungeon Siege 2, Path of Exile), but in each case I only played for a few hours and then lost interest. Titan Quest: Anniversary Edition is the first of this type of game that I've actually played to completion, and even then, I still technically haven't completed it because I stopped shortly after finishing the base game's campaign, having no desire to continue further with the expansion content. That should give you a pretty clear idea of how I felt about the game: I enjoyed it enough to play it through until the end, but not enough to keep going when it tried to get me to stick around for more.
Since I'm not a super-seasoned aciton-RPG person I can't get into much detail about how Titan Quest stacks up to other games in the genre, but even with my limited familiarity with these games I still find it difficult to talk about Titan Quest as its own entity because it seems like such a bog-standard, formulaic action-RPG that most of what I'd be saying about it could apply to all action-RPGs in general. I feel like this is the type of game that I could just say "it's Diablo but set in ancient Greece, Egypt, and China" and you would intuitively know if you'd like it or not. Still, I have some observations that might help shed some more light on the game and perhaps explain the Neapolitan ice cream comparison in the title.
