If you don't mind old DOS game, you can try the "Realm of Arkania" trilogy.
1. You HAVE to create your own party. The pre-generated ones are a mixed bunch
2. Yes, all combats are turn based
3. A good selection of spells but some of them are not so fun nor useful.
4. It is a huge world. Some town locations are not marked and you will have to discover it by yourself.
Here is the link from
Home of the Underdogs
Otherwise, get a copy of
Star Wars: Knights of The Old Republic and you might just fall in love with it.
