One of the people who ported Celeste to Stadia has talked about their experience in bringing it to the platform. Overall the experience was a pleasant now and they enjoyed the porting process. You can find the full article here.
So of the key takeaways where : –
… I would much rather develop for Stadia than any console… it’s a real shame that it’s cloud-based, because it really is a technological feat in pretty much every other regard. I just really like having my hardware and software run locally a wee bit too much compared to the average person.
On the bright side, those of us who do care can happily treat Stadia as a Linux system with the SDL lib swapped. It was pretty refreshing to have the majority of a console port’s development be almost 100% in plain sight, and not have a bunch of internal code that will vanish when the generation is over. I’ll probably look back at Stadia development fondly whenever I work on the next new proprietary console.
