Wow, stinks that I didn't find this topic until a bit too late!
Most of what I do is writing and worldbuilding. There I've got no problem building up a lore or coming up with ideas - it's my main strength. I write stories for fun, and cranking out 2000 words in an hour is doable for me (if on the high end of what I can do). For over a year I wrote a story that I released the chapters serially - 4000 words per week, sometimes twice that or even a bit more (arc-enders). Hell, I've got an "ideas file" from years ago where I'd just write down whatever story/lore drabble came to mind - at least one of these could probably be put to use pretty much immediately.
Otherwise, my main talents would probably either be mapping (whether coming up with maps or tweaking someone else's), or voice acting (which I've always wanted to dabble in). Unreal Engine 1/2 would be my main areas of experience; I could probably pick up UE3 or UE4 fairly quickly, and I've dabbled in mapping for GZDoom, to the point where I know more or less what I'm doing and I just haven't really committed to making a map yet. Unity is also a possibility - though admittedly I haven't made anything on it, I hear it's very user-friendly, so I doubt it'd take too much to get up to speed on it.
While I don't have much to show for scratch in this community, I was part of the teams for some mod projects for UT2004, specifically
CTF4 (which added four teams to a normally two-team game) and
Unreal Tournament Revolution (which aimed to recreate UT99 in UT2004). My work on both of those was mostly mapping-related; in CTF4 I was the mapping lead, adjusting two-team maps to four-team ones, and in UTR I contributed a few maps (namely the remakes of CTF-Coret, DM-Liandri, and DM-Tempest - probably other stuff too that I can't remember). Hence, I'm fully comfortable with working in a team, and not leaking stuff out - indeed, with both mods I actually learned how to do SVN, not that SVN is in vogue anymore.
Besides that, I've been part of a bunch of games' closed betas: Hawken, both Section 8 games, and Planetside 2 come to mind, so I fully understand NDAs and the like.
So if you guys decide you'd like some more people, hopefully I'm someone you could consider.
