What mods would you reccomend for IWD EE and IWD II ?

IWD2 doesn't really have much. Outside of the obligatory widescreen mod I only know of a small fixpack and rumors of an effort to port it to IWDEE's engine (via modding that is, that would probably take a loooong time but it'd be mostly worth it).

For IWD : Widescreen Mod + Auril's Bane (The Trials of the Luremaster Version) are enough. (I added the Improved BAMs, but you can definitively do without).
I don't know for ICW 2.

EDIT - I realized the meaning of EE... Auril's Bane will work only for classic Icewind Dale... It's worthy though...
