Sony launched the PSP Go today, marking the first time a major console maker has released a system entirely dependent on digital distribution. To ensure that early adopters of the $249 system have something to play on it, the company also gave its online PlayStation Network storefront a major injection of new and catalog releases. Today's update boasts more than 100 titles in all, including the first PSP Minis, Gran Turismo PSP, MotorStorm Arctic Edge, and new downloadable exclusives like PixelJunk Monsters Deluxe and Thexder Neo.

　　Since these are all newly downloadable, does this count as the biggest launch lineup ever? The newly added titles are pulled from 23 publishers (including Sony). Some companies have clearly embraced the idea of digital distribution for PSP games more than others. Electronic Arts alone added 20 games to the PlayStation Network today, from the recently released Madden NFL 10 to older titles like Lord of the Rings: Tactics and The Sims 2. Among the publisher's newly offered downloads are five different Need for Speed games, from Underground Rivals to this year's Shift.

　　Pricing for the games is also all over the map. Games just released in stores on UMDs are sticking to suggested retail for the most part, with Gran Turismo PSP, Soulcalibur: Broken Destiny, and Beaterator all commanding $39.99 price tags. Older titles are being offered for considerably less in many cases, with God of War: Chains of Olympus fetching $15.99, Disgaea: Afternoon of Darkness going for $14.99, Def Jam: Fight for New York for $9.99, and Puzzle Challenge: Crosswords and More setting the thrifty bar at $4.99. Interestingly, EA has chosen to charge more for 2005's Burnout Legends ($19.99) than for the game's 2007 follow-up, Burnout Dominator ($14.99).

　　The fist batch of PSP Minis has arrived, although the "mini" designation applies to file download sizes perhaps more than to price. EA's Tetris ($9.99, 29MB) and Sudoku ($4.99, 30MB) lead the charge as promised, with backup from Gameloft's Hero of Sparta ($6.99, 47MB), Creat Studios' Alien Havoc ($4.99, 8.03MB), and more.

　　A number of games are also enjoying temporary price cuts. Nippon Ichi Software has cut the asking price on Prinny: Can I Really Be the Hero? and Holy Invasion of Privacy, Badman to $9.99 each, while Puzzle Quest is on sale for $7.99, and niche fare like Work Time Fun and Cube are $4.99 for a limited time.
