FFVII doesn't. I pretty much plough through the game without stopping to train. It's still easily beatable. Having to train your team up too much was why I gave up on FFIV, though.
Sephiroth is made easier by the fact that I grab all the items in the Northern Cave, though. Plenty of Exp-gifting enemies encountered during the process.
As for Emerald and Ruby, I never bother any more. Got to a point where I could solo both of them just using Cloud and haven't fought them since.
