I've been slowly chipping away at Final Fantasy IV on my busrides to work, and I'm still having fun. I'm up to the bit where Cecil has just become the world most flamboyant Paladin. At one point during the fight with Scarmiglione I accidentally mashed the select button and a most wonderful thing happened. My dudes went on 'Auto' mode, which means they fight by themselves and I don't have to mash 'X'.
While, admittedly, this wasn't any use for me during the boss battle, it was of great use after Cecil shed his Dark Knight trappings and became a sap. He starts off at level 1 as a Paladin, so wanted a bit of training up. I went to the bottom of the Mount of Ordeals, switched on Auto, and preceded to destroy a lot of zombies for fun and profit. He's now level 18, and I have all the best equipment sold in Mysidia.
I suspect this will come in handy a lot later when the difficulty ramps up and I have to grind out some levels. This is my least favourite part of JRPGs, having to take some time out to mash on weaker monsters so you can mash on the stronger monsters, so being able to press left and right occasionally to get into random battles and not have to press buttons repeatedly suits me perfectly. More level-based games should have this - well, ones in this genre anyway. I'm not sure it would suit Western or Strategy RPGs much, but the ability to just set and forget for linear turn-based RPGs is, to me, the holy grail.
