So, I'm mentioning--and celebrating--it today. (With the "it" in question being the 10th anniversary of Frank Cifaldi's LostLevels.org.)

If you've never visited Lost Levels, I'd obviously highly recommend doing so now (right now, in fact)--especially if you like reading about old video games that never made it to market.
I'm pretty sure this post about Final Fantasy 64 is what first brought me to Cifaldi's site, by the way. Even if it wasn't, it's unquestionably my favorite of all of Lost Levels' posts, as I obsessed over that not-meant-to-be title far more than I'd like to admit as a teen, and the writer's insights into its existence (or lack thereof) thrill me even today.
