I agree with Spuuky on regenerating health. I actually find "finding the right tactic" to be one of the most fun parts of RPGs, while managing my health and ability uses in dungeons to be one of the more tedious. I know a boss fight is coming and I have no intention of going in at anything less than 100%, so I find myself chugging through dungeons, holding back on using anything more fun and just swilling the 99 potions I've bought.

On moral choice systems, if done well they are superb but I would rather no moral choice system than a lazy one. A particular bugbear of mine is when getting more good/evil points grants you more abilities, railroading you to make either entirely good or entirely evil choices to maximise your character's potential. What if I think the "Paragon" choice is better the first time but the "Renegade" choice is better in the next quest?
