If we want a Toady One Wikipedia page, we need to make it a campaign. They aren't opposed to one, but you have to prove the value in it.
Some things Toady has done:
Doctorate in Mathmatics
Instructing at a School
Programming several different kinds of games
Took a risk of quitting a job to become a full time programmer based only on donations during an economic slump, and is successful (so far)
So, we have some "notable" achievements, but none strong enough. But we have to beat
David Braben. we are close, I think, but until DF is released, I don't think we are there yet.
(Edit: On reconsideration, I think he might be, if combined with Bay 12 Games. we can create one and make the other one redirect. If we say he/It is notable for Dwarf Fortress, which has inspired a cult following, I think we can avoid deletion.)
(Edit 2:
Possible references to Tarn Adams:
RPRR <- Is not a "Notable" Source.
Gamasutra <- An Acceptable Reference.
Dubious Quality <- Is not a "Notable" Source.
Indie Games Blog <- On a page about "prolific or high-profile indie game developers", Possible reference in establishing Notability.
Independant Gaming Source <-Another possible reference establishing Notability.
You will note that all the "possible sources" have a place in other wikipedia articles. They are recognized as sources for news regarding things. It still isn't mainstream enough, but it is probably enough to take it out of instant delete and get it deleted from the CFD page instead.
Dwarf Fortress, by contrast, is pretty well known. It is only a matter of time, but it might not be the time yet.
