DQ Tycoon review. Classic Game Room presents a CGR Undertow review of DQ Tycoon for PC developed by Spark Plug Games and published by Encore. Riding on the wave of "* Tycoon" titles released for the PC, DQ Tycoon takes the everpresent frozen-treats franchise (boon of Little League Moms everywhere) and gives you control of the reins. Or the soft-serve lever. By tirelessly satisfying customers with an increasingly wide range of products, you'll move up in the world by managing more Dairy Queen locations (all concentrated within a couple city blocks, oddly enough) and deal with staffing issues, facilities upgrades, and... cake decoration. This video review features video gameplay footage of DQ Tycoon for PC and audio commentary from Classic Game Room's TJ.
