Similar games to Skyrim for Mac...(now and future)

Skyrim is one of my favorite games of all time. I am wondering does any1 have suggestions for open world rig isometric games like skyrim that are good and coming out or already out? I heard bad things about Ravensword: Shadowlands. Legend of Grimrock 2 seems something close.

Try Risen series, i think 1 is Mac compatible, and 2&3 can be ported :D

risen isn't for mac...any1 got suggestions?

These games are not exactly the same as skyrim but are good rpgs (on mac):

The Witcher 1/2
Divinity Orginal Sin
Star Wars: Knights of the Old Republic

The only 3 i found are dragon age, two worlds 2, and frontier.

any other suggestions of good open world rpg games now or in the future for mac? another example is bards tale

@pacific90: Honestly if your looking for good games, Dragon Age Origins, Witcher 1 and the Witcher 2 are the only ones that come to mind.

any other suggestions?
