Additional conclusions found in Winning Business Strategies for Mobile Games:

1. Though designed for devices with small displays and limited controls, mobile games have advantages over PC and video games. Mobile games can be persistent (played in short bursts over long periods), massively multiplayer, and can exploit information about players' locations and proximity to each other.

2. Mobile operators must be involved in the development and promotion of mobile games. Content aggregators will assist them in selecting and licensing the best mobile games and related content. Billing clearinghouses will help ensure mobile games are affordable and available.

3. Mobile games, ring tones, and screen savers are powerful tools for promoting consumer brands. They enable advertisements that are mobile, two-way, and contain built-in user endorsements. They enable customers and fans to create communities around favorite brands.

4. There is no clear winner yet in the competition between J2ME and BREW. Both permit downloading games over-the-air. While J2ME offers a more open environment, BREW is more secure and enjoys a modest time-to- market lead.

5. There are opportunities for game-centric mobile devices. The success of GameBoy and the first mobile phone games suggest there is large market for handheld games that are "always on" and can be played out on the street.
