It looks like a StackExchange site, but it doesn't have any StackExchange information, so is it just a clone site dedicated to all-things-games? I wonder if there could be any potential confusion between this site and that one?
SmarterGamer was started independently as a StackExchange site. However, SmarterGamer was notified a while back that the site would be getting shut down in favor of this site. See: http://smartergamer.com/questions/790/site-going-away
Not sure when that will actually happen, though.
Those questions are mine, both here and on SmarterGamer. I was simply transferring over ones that either didn't get answered or didn't have completely satisfactory answers. I was considering transferring others (at least ones I asked). Seems a shame to lose the knowledge if that site goes away.
As a follow-up to Todd's answer, it seems to be common practice to merge in SE1 sites (Chip Hacker got merged into Electronics and Robotics, Basically Money got merged into Personal Finance, etc.), so assuming that happens here those questions won't be lost, they'll just become part of this site. I'm not sure what that means for reposted questions; we might have to manually close them as duplicates
