Does your mom miss those classic card game nights around the kitchen table? Fire up UNO on Xbox Live Arcade. Is she a tad overprotective of her offspring? She might relate to BioShock's Big Daddies (yes, we get the irony). Does she dig cooking and adorably mispronounced English? Then it's Cooking Mama all the way.
Of course, for moms who are less than avid gamers, there are also a plethora of excellent casual games out there. Titles like Peggle, Diner Dash, and Puzzle Pirates could prove to be perfect distractions for the mom with a lot on her plate. Happy Mother's Day to all the Joystiq-reading maternal units.
