I think SquareEnix. Multiple HD-2D remakes for the Switch and some exclusives like Triangle Strategy. Some people might counter-claim with Final Fantasy, but there is already an agreement with Sony on that franchise back in 2001. In return, they did release Dragon Quest 11 which is also a great game from a huge franchise.
Square did nice too, their biggest misstep was releasing Kingdom Hearts as cloud-only, I'm still perplexed they will port Nier and not KH. I would understand KH 3 by the others...
I will always hope they release a spin off, but it's not coming I guess. Dream drop distance is from 2012 and no rumors of any spin-off ever since
