In response to communication from the Nexus Staff, BioWare's Dragon Age development team provided their perspective on this issue.
Their basic position is:
BioWare will allow relatively free use of its in-game resources (models and textures) from Dragon Age (all games) by modders who wish to create new content for use in the Dragon Age series.
BioWare requires three things:
1. Mod must be totally non-commercial. There can be no payment specifically for the creation, use, or distribution of any mod using BioWare’s assets.
2. Mod author must have a legitimate copy of the source game/DLC from which the assets were obtained.
3. Mod cannot recreate any DLC adventure itself. In other words, a modder can use a DLC asset in a new work, but can't simply remake the whole thing.
This is not blanket authorization to take anything and everything from Dragon Age and use it in any way one wishes. As always, modders need to respect the copyrights / IP rights of others, including other modders, and observe the terms of the EULAs associated with any hardware or software. When in doubt, ask permission!
We here at the Nexus want to thank the BioWare team for their very liberal policy. This welcomed stance in support of the modding Community is very much appreciated.
