Some feedback on those points
- Resting
I've always thought that resting kills flow of the game, it seems to kill any momentum, when you've got to stop to rest. Maybe mana isn't an answer , some kind of cool down mechanic would be much better. But keeping your party rested is dated idea, sure it's realistic etc but it bores me to death. There was a GTA game in which you had to eat, work out etc it was hopeless for me.
- Familiar
I would love familiars to be part of a game, but change with your characters, for example if characters is bad familiar makes some kind of nasty deeds(maybe changing how they look as well). Making them some kind of character avatar would be cool, as long as they're not very powerful.
- Dialogue
I'm not sure, I would be totally satisfied with rich and interesting dialogues and don't really care how it'll be executed.
- Romance
cool option as long as it is executed well, it would have to be complex and well constructed unlike BioWare games.
- Story
I would love it to be something special, there are some memorable stories in history of the games ( Metal Gear Solid, Knight of the Old Republic, Planscape Torment, Heavy Rain, FFVII) I would love this project's story to be among them. I hate how cliche and uninteresting main plot in games becomes - take DA:Origins - great game with some interesting ideas, cool combat system and many memorable side quest but somehow ruined by stupid - evil rises, demonic invasion, lone chosen by destiny hero to save the world crap.
- Races and Monsters
keep in simple, traditional fantasy races are cool, just make your own spin on them, add some other races and it would satisfy everyone, I would love it to be ultimate RPG and Elves, Dwarves are part of it, but I understand that some people are sick of those races, so be keeping some traditional races while adding some new ideas would be very cool.
- Classes
The more classes the better but why to chose them ? Think about a system which automatically make you this or that. For example you choose as a spell caster and then start playing as a fighter - that automatically make you a mage-warrior classes(name it dragon mage or whatever) giving you access to some new abilities. Be using backstab, decoy , poisoned weapon and having evil personality in time your character becomes an assassin and is able to specialize even more in that department. And unlocking classes should be made automatically without information how much more you have to do to obtain certain class.
