Not sure if there's going to be the same as last week where half of the games aren't unlocked til next Wed. but here's what was in pack4 today.  
 
time pilot, asteroids, demons to diamonds, grand prix (2600), shark! shark!,  space duel, stampede 
 
Pretty sure that's all of them for this week, time pilot makes the first cross-over title from XBLA. Note that the space duel game & shark! shark! both were a little wonky on the controls to get them to work. Neither were all that great IMO but some might find them fun, just keep at the controls to get the game started (for shark! shark! try the keypad for the intellivision controller, somehow got it working that way).

Good point, time pilot is the only one that I bought for XBLA & knew about.    

Still no River Raid, huh?  Well that sucks.  Awe well, that just means it'll be another week before I'm out another $3

Well Microsoft has suspended my account for reasons completely unknown to me, until the 30th which means i can't buy any day one games which means i won't bother getting any that are coming out on the 27th at all...was gonna get Millipede but then again i hate the controls in Centipede so maybe it's a blessing in disguise.

Since I was out last week, I'll probably do a double-length Game Room quick look this week to show off last week's stuff. I thought that I had played Demons to Diamonds before, but I was thinking of something else. That game's weird.

Yeah, very much enjoy the Game Room quick looks!
