I've been playing Grim Dawn recently, and after the intial high hopes for the setting and story it all kinda petered out rather quickly. The gameplay itself is a refined and improved version of Titan Quest, so that's still pretty fun, plus they have some really neat systems in place that tie in with crafting and factions that I'd love to see in some other ARPG's. But that's not the peeve. The peeve is something that I've noticed and when I started thinking about it some more I realised that holy shit every ARPG that I've played to date has had the same basic set of enemies, with maybe one or two unique things, regardless of the setting.
You have zombies, usually early on, sometimes mid game, they may not always be just undead but they're zombie like in behaviour and looks for the most part, wether they're made from regular corpses, revived by otherworldy spirits or bodies possessed by angry spirits or whatever. Then you have your run of the mill skellingtons, nothing too fancy for the most part, but every setting has them.
Then there's the giant insects, usually spiders, sometimes something more creative like wasps or whatever. Also wild animals, which will always be driven to agression by whatever calamity is happening in the world, usually something dog like and something birdlike, perhaps a pig of some sort too.
Tying into that there'll always be some sort of beastfolk, depending on the setting and your current location within the setting you could be bashing in snakepeople, spiderfolk, some sort of cat combo and of course everyone's favourite, the fucking harpy.
And finally the garden variety of orcs, goblins and trolls. Of course they're rarely call them exactly that, and they'll maybe give them a nice paintjob but an overused archetype is an overused archetype, no matter how much you try to hide it with paint and shiny bits.
ARPG's, really shitty and bland settings once you think about them for a bit.
