I recently bought Deus Ex GOTY and I'm curious about something. Is there any way you can use the Deus Ex Enhanced mod without the Shifter mod? I want it for the hi-res fonts.

Hi-res fonts? The game scales the UI so at high resolutions it should look pretty small and stylish. There are mods just for the UI if you want it larger... you won't want it bigger.

I would suggest using the Deus Ex DX10 EXE, which is awesome, and the recent texture replacer that closely follows the original texture look. Keeps the game looking as it should but also as best as it can.
