If you've been penny-pinching to save up for upcoming games, here's a little primer on US retail releases this week, starting July 2.

Eye catchers of the week (for the grown-ups) would be Ninja Gaiden Sigma for the PS3 and Vampire Rain for the 360. We've been covering both games for quite some time now, and the anticipation is fit to burst through Rachel's black leather suit.

Moms and dads may also want to get Platinum Sudoku or Vegas Casino for those quiet times when the kids are busy with Marvel TCG and Taito Legends 2. (More about these and other games in our Full Article).

What a way to start the month of July! New month, new week... new games!

Ninja Gaiden Sigma. The demo for this ninja action adventure title was one of the few demos that actually lived up to its hype. For those who are old enough to crave challenges and gameplay more suitable for mature audiences, this PS3 exclusive is a must-buy.

• US$ 59.99

Vampire Rain. Take on the role of John Lloyd, the government's vampire hunter, as he purges Los Angeles of the vampire threat. We're hoping that this horror action adventure game will cast new light on the vampire game genre with its stealthy "high-tech Buffy meets Sam Fisher" gameplay.
