The best way to play Deus Ex
Give me Deus Ex. This mod lives up to its name. I recommend this mod even for first timers, since it universally improves Deus Ex. No critical, controversial content changes, just improved gameplay (AI, balance, augmentations), many fixes, and the most useful graphics mods that retain the original art style. The creator of this mod also created Unreal Evolution, Quake Combat Plus (an addon for Quake 1.5), Turok 2 Plus, and some smaller projects. Having spoken to him at length, it is clear that he understands game design on a deeper level than the vast majority of modders and even game designers out there, and it shows in all of these must-play mods. The only question is which version of GMDX to use. This is the latest version from the original creator. Do not use GMDXv10 - this is unofficial, unsanctioned, makes many changes that aren't as well thought out. GMDX v9.0.3, GMDXvRSD, and GMDX Augmented Edition are the only ones to consider. The only argument people provide for not using this mod as a first timer is, "It isn't what the developers intended" - a fundamentally flawed argument that ignores the fact that no game comes out exactly the way that is intended, and an argument that falsely assumes game developers are infallible. The fact of the matter is, most gamers are not concerned with what was intended, they just want the best experience and GMDX is exactly that.

If you're revisiting Deus Ex. play GMDX.
It's Deus Ex, but just that bit more polished. The skill system changes are great, with rebalanced skills and optional perks.
