Match 5 is a brand new Intellivision game, complete with professionally produced box, manual, and keypad overlays. It's a puzzler in which, as the title suggests, players match rows of five items to make them disappear. You can order the game, which I've played and thoroughly enjoyed, on the Elektronite website.
Freelancer Derek Slaton, who I met at the Retro Game Fest in Austin, has written reviews of every U.S.-released Sega Master System and published it as The Sega Master System Encyclopedia. Unlike most self-published books, this one has full color illustrations throughout (though you can order a cheaper black and white version). Derek is a nice guy, and you can order his book through his website.
The History of Sonic The Hedgehog is a gorgeous hardcover that does an excellent job giving a certain Sega mascot his due. Every great video game character, from Pac-Man to Mr. Do! to Q*bert, deserves such a book. You can order The History of Sonic The Hedgehog here.
