As a lot of people know, Bethesda just came out with their Creation Kit for developing mods to Skyrim.
I've been developing for a while, I have a couple of games released including one that's doing well in the App Store. My goal is to get a job at a studio like Bethesda, Bioware, or Valve. Right now my work shows I can do some of the harder parts of a game engine, but I have nothing directly in the RPG field which is where I want to be.
Would building a mod for Skyrim help my resume enough to justify the time it takes to do it, or would my time be better spent making another non-RPG game from scratch? This mod would be a full side game completely separate from the game's world. My usual thought of mods is they are for fun and don't really help the resume as much as more raw projects, but with how open the creation kit is, it seems you can really go a long way in development.
Before I get any duh or subject to opinion answers, this question is about my lack of knowledge on the perception of notable mods to games. My assumption is there is a general consensus to if mods can be impressive and help a resume which already has some (decent) content for the level of job it's after. Also, I have no intention of starting an RPG from scratch if anyone is crazy enough to offer that as a solution, this is for my resume only.
Lets assume the mod I would make would be impressive for a mod. If that was up for debate, the answer to this might come out a bit gray.
