Another option could be to try a mod Deus Ex Revision. I played both versions, original and Revision, and certainly it's worth a try. Story stays the same but Revision introduces a lot of cosmetic changes which aims to make user experience closer to modern titles.
Revision includes some existing modification but team also added their own work. General changes includes, as below.
- Improved textures.
- Improved models - player, NPC, robots, weapons, etc.
- Improved environment - more detailed maps, some level changed completely.
- Improved soundtrack.
