I beleive Bethesda outdid themselves with the Creation engine, Radiant AI, and Skyrim, in general. But I wonder if it wouldn't be an issue to consider the following.
-add the ability make and enchant arrows;
-allow companions to learn spells by option in their inventory;
-area-effect healing spells;
-healing spell IFF (I'm tired of healing my foes while healing my companions);
-ability to enchant items with improve enchant skill;
-companions dying (change to unconscious);
-craft spells;
-all potions and scrolls weight (all weigh 0.5; vary the weight)
I really like Skyrim and it's more challenging than Oblivion, but there is still some thing missing. Please consider and thank for your time.
I very much agree about the dying companions. That is stupid. They should go unconcious.
There should be a more focused healing spell.
The potions, might be a good idea. If it was universal then it could be good.
It does'nt need arrow making or enchanting though. The effects in the bow.
You don't need to be able to make spells. That would be too complex to do.
Companions are ok without being taught stuff. That is for a more rigid system like Dragon Age Origins.
I wish you could get effects from duelwielding 2 magics or magic weapons. Like on Dungeons And Dragons Online and anywhere else it is in DND.
There you get Steam from using a fire weapon and a ice weapon. A enemy can be immune to fire and ice, but nothing is immune to steam.
