...That a lot of Ocean's 16-bit games (I.E. Amiga, SNES, VGA DOS) make use of a simple, color gradient background?

I'm not sure if it was because of software limitations, time constraints, or they just thought it was easier to work with, but it's pretty interesting to say the least.

P.S: What's your least favorite Ocean game?

No offense but you basically just answered your own question. DragonDePlatino gave a pretty solid reply, too.
At a guess gradients were used because they saved time and were relatively easy to pull off, too.
