Im not sure how you are planning to do the fighting
but Im dreaming for a long time about a RPG where we can assign our own combos to our mousebuttons
everyone could have his own unique fighting style and change it so it feels natural for every player
and as your level increases you unlock different combos/skills to use with those combos
because in my opinion most RPGs are just about clicking on your enemys and you need no skill (often just a high lvl, or a good armor)
and that is getting old and boring to me because I played tons of RPGs just like that.
but please at least let us use combos and not always the same attack over and over and over and over again

You'd like Legend of Dragoon on the PSOne, a similar game to Final Fantasy. Each attack is a combo and you have to press buttons at the right moment to progress the combo. Every 20 times you fully complete a combo, it levels up giving greater bonuses. As your character levels up, more combos become available.
