Didn't Grim Dawn just come out with an expansion like last week also?
About a month back, yeah. Two new masteries. Two new acts. General "more of everything" type improvements. Personally, I played about half an hour of Titan Quest and switched over to GD instead. I'm sure I'll eventually go check out the new TQ content, but other than actually having non-muted colors in its palette, I don't see what the selling point for TQ is over Grim Dawn other than more nostalgia.
Mechanics-wise I like Grim Dawn more and it has a number of QOL improvements over TQ, but man I just don't think that Grim Dawn expansion is good. The content is just bland. The level design is crap, there's nothing interesting about any of the enemies, and there's not really any theme to it. Honestly the base game can be enough of a slog to go through after the first time that adding another act onto it that's just more of the same almost feels like punishment. Haven't gone through this TQ expansion yet but I'm hoping it's at least slightly more interesting.
Decided to go with a sword & board Conqueror (warfare and defense) to replay the game. Speccing Defender first helped a ton with getting over the hump of the early bosses, although DPS is troublesomely low. Once again, the biggest issue I have with this genre is choosing a build and sticking to it.
