Since there is no subforum for the demo with sugestios for the final game i decided to make one here.
Some are gameplay oriented some are graphics-wise some game-wise.
Graphics:
-allow option to disable shadows completely. They require a lot from video cards in any game and thus there should be an option to disable them.
-allow an option to disable day/light cycle (I know this add to the feeling but the game has a lot of feeling as it is). Of course in the caves it should be dark

.
-also i'm not sure but i think game comes with anisotrophic enabled from the beggining and from what i seen the game looks great on the lowest details so add an option to turn it off.
Gameplay
-replace the save button with save and exit.(i really don't know what the game does if you don't save before exiting but i guess it takes you to the last save. If you make this change i also sugest an auto-save feature on leveling/entering a new area/tp-ing to city so if anything happens and game crashes (or power failure, anything) you will not loose all your work.
-when you place your mouse over a band you just recieved it shows you that one and the 2 you have so 3 windows, i think the 1-st and the 2-nd should be reversed so you see them as they are on your char. Now the right window shows the left band/loop and the right windows shows the left band/loop.
Game
-I don't know how it works but the multiplayer should be connected via tcp/ip (i mean to be able to play over internet with the ip, whithout connecting to the gamespy servers (IIRC this is how the battle-net is made)).
-Also in mp the map should show you the location of your party members(like the quest markers and such).
Will update as i see.
