“Halo: Reach” beta (no rating, requires “Halo 3: ODST” or code to play): Easily the biggest thing going on the Xbox 360 this weekend. I had a chance to give it a try early and posted my thoughts here.

“Fat Princess: Fistful of Cake” (rated E, $20 on PlayStation Portable): This is a portable take on one of the PlayStation 3’s most under-the-radar online strategy titles. Your team needs to rescue your princess from the opposing team, which has been feeding its captive forkfuls of delicious cake, making her fatter and much harder to escort. It’s not a straight port, though. This budget-priced title actually packs in more maps, more game types and extended single-player story compared with the PS3’s download-only release.

“Call of Duty: Modern Warfare 2” (rated M, $60 on PS3 or PC): The Stimulus Pack that hit the 360 several weeks ago is finally available for PC and PS3 gamers to buy. $15 gets you five maps, two of which are remakes of maps from the first “Modern Warfare.”

“What Did I Do To Deserve This, My Lord!? 2” (rated T, $30 on PSP): This is the sequel to the game that was originally called, “Holy Invasion of Privacy Badman! What Did I Do To Deserve This,” but that’s not really important as “My Lord 2” includes the entire first game as unlockable content on the disc-based, UMD release. Kind of a hybrid of puzzle game and role-playing game, this thing’s got cult classic written all over it.

“Picross 3D” (rated E, $20 on DS): Nintendo’s single-player puzzle game adds an extra dimension to things. This one’s a bit outside of my wheelhouse, so I’ll let Joystiq’s review do the talking.

“Prince of Persia” (rated T, $30 on PS3): Though this is available on other platforms, the Epilogue downloadable add-on is on sale on the PlayStation Network for half-off, or $5. Then again, the game’s $10 cheaper on the 360, so there’s that.

What I’ve been playing: I’ve got a week-and-a-half out of the office, though I’ll still be blogging some. On Thursday, I checked out a preview of the PC build of “Mafia II,” but what I saw is under an embargo for a bit, so you’ll have to wait on my impressions. Once I got home, I unintentionally made it a 2K Games theme night, playing some “Borderlands” with a buddy and then unwinding with some “Civilization Revolution.” My wife and I are going out tonight, but when I get home I’ll be playing some combination of “Alan Wake” and “Splinter Cell Conviction.” It’s possible the new “Left 4 Dead 2” downloadable content will get a workout sometime in the next few days, too.
