Dark Souls should be a real message to any developer. Heck, that game came out so broken, and was 'fixed' within such a short time it was embarrassing. And it was supposed to have taken the guy (Durante, was it?) about 13 minutes to do it. There's no excuse for this nonsense, really. And Arkham Knight, that took so long to get it right, what a mess. It seemed to far along to scrap altogether and do again, yet nothing seemed to be able to fix it. I got it eventually when it was cheap and played it on my GTX 970 with very little stutter, so I guess I was one of the lucky ones by the end.
For some reason, every time people say "the controls were designed for console", or "play it with a controller on PC", I always expect to have some miserable experience. I do play many games with a controller on a PC, but on those claims, I somehow always end up playing KB & Mouse. Such as, Witcher 2, Fallout 3 and up, X-COM, Skyrim. Never gave me much trouble, except for Skill/spell/weapon wheels. Which you can usually bind to numbers, if the port was done right.
