I think this is quite unique, I haven't seen any other games where you can do that - so I'm not sure why you are saying games are doing this?
1) Icewind dale 1
2) Icewind dale 2
3) Neverwinter nights 2 Storm of zehir
4) Wasteland 2
(and Original Sin 1)
Although this system allows you to create good combat, does not allow to create a good story.
