Real time systems are good, with the right game. I don't like the idea of a real time battle system with an RPG.
Secret of Mana, Secret of Evermore, Tales of Series, Star Ocean III, Final Fantasy XII etc.
No I can't see real-time battle systems working with RPGs either.
They wouldn't change the battle system anyway since I imagine that there would be a fair bit of backlash towards such a decision and wouldn't be well accepted, the people directly above show this.
