One of the biggest issues for Tremulous in the past has always been a huge lack of publicity.
I probably shouldn't be telling them what to do, but it would do good for the company to try to impress reviewers like IGN, because that's pretty much free advertizing if they can make it even close to the front page.
If AAA Games plans on making games other than T2 in the near future, the best thing they can do is try to raise capital and bring as much attention to themselves as they possibly can... this means contacting reviewers, making YouTube promos, etc.
Selling the game through Steam is a great way to keep saleability up over the long run as well, if they can make an agreement with them. Steam has a huge variety of buyers in a very small web space, which makes it a great place to be an upstart company.
If they can reach 5,000-10,000 copies in a year at $15~$30 per copy, that's money in the bank.
Not to mention the $40~$80 Collector's Editions if they do decide to do something like that.
