instead of getting the Level cap mod you can always just type in game in the console command by presing ~  and then typing: setgs iMaxCharacterLevel 100, which raises your level cap to 100 or you can put whatever number you want, but you do have to type it in every time you start the game

While mods for these games are cool, I found that for Oblivion I ended up only using graphical enhancement and bug-fixing mods in the end.

Since I'm playing New Vegas on console, I wish they'd hurry up and release more fixes. That's really all I want. If it could run and I didn't have to worry about the game randomly crashing I would love it even more!

" Some mods that I have been using and didn't see mentioned already:
 
DarNified UI NV
This was my favorite UI mod for Fallout 3 so I am glad that it is being done again for NV.  It streamlines a lot of things and makes much better use of the screen real estate provided by higher PC resolutions.  It is still in beta so he only posts it in the bethsoft forums instead of the nexus (although it doesn't look like a beta to me!).

Separate boxes for DPS and DAM?  I'm in.

Last night I found the Sack of Holding mod. I loved this in Oblivion, so I thought it was great to have one in New Vegas. I am a hoarder and I keep 1 of every weapon and clothing so it's good to have a portable storage device.
