I would not play with any huge gameplay changing mods for a first run, so I recommend the Unofficial Patch, NV Script Extender, Anti Crash, NMC's texture pack, Nevada Skies, and Populated Casinos (unmodded the Casinos have almost no NPCs in them lol). These mods will help you have a much smoother experience and the graphics mods pretty it up a good deal
