The IFWiki also linked to a pretty large set of 2005 IFComp reviews, and I looked again a day or two ago (probably as this topic came up) and saw similar links for 2004 (edit: looks like review lists extend to even more prior years now). It’s a little different deal, since the links branch out to the reviews elsewhere, but any archival or centralized collection of links is a great idea. I’ll often go back to hunt for and re-read reviews of my past games, and that makes it a lot easier.
