Earlier quoted context omitted.
It's complicated. Keyboards are almost certainly 'better' in the abstract if they're good enough (low activation threshold, not a lot of bus latency on whatever you're using to connect it, etc) because it's easier to press complex sequences of buttons when you're not holding the thing you're pressing them on ('fat thumb') or you can choose the layout of the relevant keys (vs. 'claw' or 'piano' gripping a controller).…
>A lot of games do require controllers that are at least no more capable than one that came with the console though. An example of this would be if the original controller won't let you press both left and right at the same time, and being able to do so gives an unfair advantage due to the way the game was programmed (I think Castlevania SOTN is one of these.)
Re: Super Mario Bros: The Human Limit
#41Fun story: when I worked in videogame QA ~20 years ago, there was a specific Nintendo rule about games not doing anything weird when both left and right were pressed on the controller at the same time (this would have been Nintendo DS, I think). This wasnt possible on a normal console, so how was it tested? We had a special unit that someone had cut the Dpad in half down the middle with a Dremel tool.
