Deus Ex: Revision on Steam
store.steampowered.com
Deus Ex: Revision is a community-made overhaul of the 2000 classic. It features new environments, music, world-building detail, and bundles in some of the best modifications the fanbase has made, including Direct3D 9 rendering, high-res textures, high-detail models, and alt gameplay modes.

I thought I would call attention to “Deus Ex: Revision”; a well-tailored, free mod suite available on Steam.

I used it about a year ago and it was a great way to re-experience the classic first game on modern PC hardware with tons of optional tweaks and graphics upgrades to take advantage of.
