Development for Switch should still be cheaper than PS/Xbox though as the level of graphical complexity is less. Rise most likely cost less to make than World for instance.
Also, said Switch games don't need to be AAA, it could also include AA stuff like Team Sonic Racing and Yooka Laylee and the Impossible Lair where it seems the Switch version was the lead.
No game needs to be what the internet calls AAA. In most cases what internet calls AAA to me means bland and boring but pretty.
Focus on gameplay mechanics FIRST and sort story and visuals SECONDLY, and dare to do syalized graphics instead of ”realistic”. This is exactly why Nintendos games crush the competition on a single system.
