I thought the way BG II implemented Wish & Limited Wish was OK, where you get a dialog menu of various choices. I edited the 2DA table a little bit to favor my preferred options, and now I really like using Wish in BG II with my wise mage.
I hope Wish shows up in the first release of BG III somehow. In the old D&D Module G2, Glacial Rift of the Frost Giant Jarl for character levels 8-12, there was a Ring of Three Wishes.
