Starting today and running until December 8, a new 99 cent game will be featured everyday on the Games for Windows store, Microsoft announced in a press release. Additionally--also running until December 8--gamers can purchase a copy of World of Goo for $4.99 (75% off), as part of the site's "Deal of the Week" promotion. As an added bonus for purchasing the fantastic title, players can unlock Achievements for their Xbox Live/GFW account--presumably to show off their goo-management prowess.

Each daily deal runs until 8:30am PT the following day. Stay tuned tomorrow for another 99 cent special during Microsoft's new promotion.
