I see what you're saying, but I'd not be happy playing a PC game in this decade with no talking. They could always have text and voices, and the ability to use either/or or both.
In any event, I think it's safe to assume they will have voices for the NPCs so I hope they don't just use the same ones over and over again like in Oblivion. That just gets irritating, and it's even worse when the same character says different things in different voices.
i agree. and besides there are only a few difference between how morrowind and oblivion did dialog;
-remove the chat log
-remove 90% of the topics
-restrict some topics to conversation trees
-add voice acting
and you get the oblivion dialog system.
this is issue is really just a false dichotomy when you think about it, spoken dialog doesn't have to be along the lines of oblivion and written dialog doesn't have to be along the lines of morrowind.
Realism:eating, sleeping, etc.
I've said this recently but i think any sort of realism limitations should be handled with buffs and debuffs so that your not strictly required to eat frequently, under punishment of death, but you will notice that your character isn't performing as well as it did when it was well fed. essentially something like that fact that you currently move slower when your carrying a lot of weight.
i think the ability to "tweak" known spells would be interesting, at a cost of increased mana or cast time, be able alter the magnitude, duration, effect range, maybe even the delivery method(touch, target, etc)
more delivery methods:
aura: damages close enemies
ground: damages enemies that enter specific area
chain: jumps from one enemy to another
spray: directable damage(flame throw esq)
