_ChaosFox_: So, what exactly was YOUR point?
My point is, that I would have wished for such a post in the first place ;-P
_ChaosFox_: So regardless of the licence in question, it's educational so it falls under fair use.
I was thinking about this too. In Germany you're probably right (although there are also some restrictions for educational use; depends on the specific use case I'd say). It looks like in the UK it's a bit more complicated. At least most universities make far more fuss about copyrights than in Germany. That might be a good source for the OP btw (@LOSTSOUNDZ: Check for info on your university's homepage regarding copyright).
_ChaosFox_: The assets are under a Creative Commons licence (CC-SA-BY-4.0), so even if the OP chooses to use Warsow assets and even if it wasn't for educational purposes, it'd still be allowed.
Warsow's EULA clearly states that artwork, musics, dialogues, stories, names, 3d models, etc... are under a proprietary license - reuse prohibited. This isn't uncommon, open source often only covers the code and not the artwork.
Regarding Deus Ex, their Eula is pretty clear as well:
3. Restrictions
You are not permitted:
[..]
(b) except as expressly permitted by this EULA and save and to the extent in the circumstances expressly permitted by applicable law, to rent, lease, sub-license, loan, exploit for profit or gain, copy, modify, adapt, merge, translate, reverse engineer, decompile, disassemble or create derivative works based on the whole or any part of the Software Product or use, reproduce, distribute, translate, broadcast, publicly perform, store in a retrieval system or otherwise deal in the Software Product or any part thereof in any way.
[..]
Your use of this product/service is subject to the GOG User Agreement.
"expressly permitted by applicable law" might be the key as you stated. If it covers OP's use case of educational usage, it might be possible, but he would pretty sure never be allowed to give his final product to anyone outside the pure educational context.
The last sentence shows what I mean with GOG's installers. It's not about ownership, but about what you are allowed to do with the product.
