Tough decision. $5 for L4D2 is amazing, but a Valve complete bundle with a discount on top of it is robbery. Depends on how much you want to play the other Valve games.

Personally I'd go for L4D2, because $5 for it is really low and you don't know how much the Valve bundle will cost on the holiday sale. If the Valve Bundle does indeed get a huge sale on christmas, and you buy it, you won't lose the L4D2 copy you got before, instead you'll have 2 L4D2 copies on the same account, and you'll be able to gift one of them to someone.

actually that was wrong... unless they ammend the rule at xmass

in short no, only HL2, HL2E2

(I got an extra HL2 like that and gave it away, but for example I had EmpireTW from the TW pack and I bought the Empire/nap bundle and didn't get an extra copy... no matter I bought it for Nap and all the DLC included (was the same price as nap alone ^^ ))

Not buying anything from today's deals, although the Indie Energy Pack tempts me. Bought a Canon PowerShot A3100 IS Digital Camera from Amazon so I have to use my remaining money wisely.

Out of curiosity, what is everybody's top 5 games from their wishlist?

Mine are:

Fallout 3: Game of the Year Edition
The Witcher 2: Assassins of Kings
The Last Remnant
Guild Wars Trilogy
Sword of the Stars: Complete Collection

I bought Shatter for £1.75 (~$3) during the Summer sale and would gladly have paid $5 for it alone. It's an excellent Breakout-type game with a superb soundtrack. I don't know much about the other games, but I've heard good things about Puzzle Dimension and Tidalis. Bar Droplitz, all the games have demos available as well. Think of it as getting Shatter plus 4 free games and you can't lose.
