After playing Dragon Age so many times, I'm pretty sick of being railroaded into taking Wynne through the Circle Tower with me. I mean, what was Bioware thinking? The only two choices you have are to  murder her in front of a bunch of kids or drag her along with you? Where's the sense in that? And from what I've seen on the message boards, I'm not the only one who's tired of being stuck with her. Yet, while a couple people had suggestions about how a mod might fix this problem, no one seems to actually have created one.
 
Which brings us to... my very first mod!
 
This is just a simple override. I modified scriptgen00pt_party so that Wynne joins you, but isn't locked in. Add her to your party, have her drop the barrier, and then switch her out for whoever you want. The rest of the quest will play out exactly as it always does, and she'll be waiting for you at your camp when you're done. Or, if you need her to help fight Uldred, you can add her to your party after the Fade, in the room where you take the Litany from Niall's body. Either way, everything else plays out just the same.
 
Installation: Just extract the folder and drop it into your Documents/Bioware/Dragon Age/packages/core/override directory. To uninstall, just delete the folder.
 
Compatibility: Any mod that changes files gen00pt_party.ncsand gen00pt_party.nss will conflict with this, but I've got about 50 mods and none of them seem to use this script. But if you find any that do, please let me know and I'll talk to the author about it.
