I like them on console but am indifferent to them on PC. It might be the little ‘ding’ that provokes a Pavlovian response.
They have their place; Mudrunner was undoubtedly made more enjoyable for me as there was a trophy associated with completing the main task on every map. So it made the mundane task of hauling logs to a crappy lumber mill, well, slightly less mundane, I guess, but also capped off each map in a satisfying way. Ding!
When they are done well, they can be really good, adding a lot to the game (making you switch your playstyle, making you fight bosses, revealing depths to the game that you may not have known existed). The prime examples of this latter point are Demon’s and Dark Souls I. 100%ing those two games is an incredible experience, because it makes you experience the game to the utmost. (I’m a bit hazy on the Dark one, so don’t ask me for specifics there, but I remember feeling that it approached Demon’s in quality).
There are sites that revolve around tracking and competing for achievements, with blog posts, events, communities etc, so while I’m not interested in the social aspect per se, it’s an interesting scene for some people. I think these are mostly console-based.
I don’t know why PC-based achievements don’t do anything for me. Maybe we should petition them to add a sound?
