Ohhh, these take me back...
nitin, yes. Quake II was released in late 1997, about 1,5 years after Quake. Thusly 1998, until Half-Life came out much later that year, was all about Quake II. Tons of great levels, both single player and multiplayer, the release of the 3.14 patch that finally added some official deathmatch levels to the game, not to mention CTF.
Matt Sefton's Single Player Quake 2 Level Heaven (which also has The Bloodshrine, The Azure Mines, Abandon All Hope and Arkanian), crash's review site (the name and address eludes me), and even Talon's Strike all prospered that year.
I still remember all of the levels mentioned in the news post, except for 666.
Of course, from the modern point of view, there's really nothing special about those levels. However, the first six months after Quake II's release could be considered its Golden Age. Later levels are somewhat better, but the quantity and quality was still very high back then, and new levels were released weekly. Something magical about that spring.
Back when 800x600 was enough.
