SMT usually does it fine, the health totals always remain the same and it's usually enemy damage output that's increased. Occasionally store prices, which is a bit more annoying.
Strategy RPG's also tend to be fun on hard mode, like with Fire Emblem, where you don't really have to think unless you're playing one of the harder difficulties.
