I recently (finally) got a Xbox controller for my PC. What Steam games are must-play with a controller rather than M&C?
I'll tell you a weird one,
Caves of Qud.
It's a true Roguelike (not the modern usage, the old "a game that works like Rogue/Angband/etc."), and it's incredibly good, well-written, clever, really shockingly good gameplay, insane replayability etc.
But the oddest thing about it is that it has an incredibly good controller setup. Most Rogue-type games are very heavily keyboard-based and use a large number of keys, and you
can play that way, but... don't. The controller just makes it so much more pleasant to play and so much more intuitive after even a few minutes.
Re: Soulslikes, I would say maybe don't lump
Elden Ring in with the rest unless you've played it, because I think for a lot of people it removes most of the most disagreeable-to-them traits of Soulslikes (particularly getting stuck on some unavoidable boss). However if you just hate RPGs which don't have quicksave/quickload, or third-person RPGs, then fair enough you'll dislike that too!
As for other games, well:
Pretty much any Metroidvania or platformer goes from annoying to much better with controller.
Third-person action games as noted.
Fighting games basically require a controller. (
Absolum and
Teenage Mutant Ninja Turtles: Shredder's Revenge are both extremely good single-player or co-op sidescrolling beat-em-ups)
Games where driving or flying are a significant part of things benefit hugely from a controller - you might enjoy for example the very chill
Snowrunner, which about driving big heavy trucks and 4x4s and so on very carefully in snow and mud with realistic physics (not racing to be clear, it's mostly doing tasks, like transporting goods or towing other vehicles or the like).
JRPGs - The best recent one are
Metaphor: ReFantazio and
Expedition 33, both of which are tremendous.
Probably think of more later.
