Squaresoft anyday of the week. Hironobu Sakaguchi created Final Fantasy and was directly involved with every FF from 1 - 10. 10 was his last involvement as an Executive Producer. After that FF went to crap. And is the diabolicle mess it is today. Kingdom Hearts was also among direct influences from Sakaguchi as was Vagrant Story.
He was so influential that Kingdom Hearts character Master Eraqus was made to directly resemble Sakaguchi as an honour to him.
He made Square, and him leaving has destroyed them. The last 3 Square games Ive played are but a shell of thee former games. I wont ever waste money on a Square game again. FF13 was absolutely terrible.
