FF games are a solid choice. The Pixel Remasters have been very well received and anything that makes the early games more approachable is a solid win in my book. That said, I personally found the 3D version of FFIII (actual 3, not 6) to be phenomenal.
Only thing better is finding commented out code below that which would actually prevent it from running in Prod. Bonus if there’s a code comment next to it saying “disabled per email” with no further explanation.
