I love time management sims, but I'm not sure that's the best name for them. It sounds businessy and important, the kind of phrase you'd hear in an office where everyone's watched too much Apprentice and keeps banging on about driving the pivotal endpoint forwards. It's not suited to video games about dashing round diners and running beauty spas where all the customers are cats.
A more appropriate term, I think, might be plate spinners. That's because these games are all about maintaining momentum while multi-tasking. (This is the moment to insert a searing feminist diatribe about the reasons women are so excellent at playing them, but I've got to finish this article and hang the washing out before my husband's Super Noodles boil over.)
Sushi Go Round is one of the finest plate spinners I've played. Actually it's more of a plate pusher if you want to get literal, but that's probably taking things too far. You play as a chef in a sushi restaurant, doling out menus, rolling up raw fish and bunging the finished dishes onto a moving conveyor belt.
