The latest game to join Origin's "On the House" program, in which Electronic Arts hands out free games, is classic simulation-strategy game Theme Hospital. Bullfrog Productions' PC game, normally $4.99 through Origin, is currently free to download.
Theme Hospital is the successor to Bullfrog's previous business sim, Theme Park. The game tasks players with designing and managing a hospital, and treating patients with odd diseases. Physical and psychological maladies include Spare Ribs (extra rib growth), King Complex (the uncontrollable desire to impersonate Elvis Presley) and Bloaty Head (oversized craniums). Theme Hospital was released in 1997.
To download the game, you'll need an Origin account. Previous "On the House" giveaways include Dragon Age: Origins, Peggle, Wing Commander 3, Dead Space and Battlefield 3.
