You would need about 200 Centers before any large publisher would talk to you, as well many have signed exclusivity contracts with I-Games, meaning they are the only organization allowed to manage their license to game centers. A perfect example of this is Howie's Game Shack, largest game center company in the USA, maybe North America. They had originally not joined I-games and were working with EA on events and games. I-Games informed EA that Howies did not have a license and they were in violation of their agreement with I-Games. EA stopped all activities with Howie's and Howie's had to join I-Games to get licensing. Now if a company that has 1,500 stations cant work directly with a publisher on licensing a company with 100 stations probably will not even get a call back.
On another note when it comes to licensing, the I-Games license cost about $25 per publisher to get, were as if you look at licensing that has just come from publishers it cost a whole lot more. Blizzard is a perfect example, it is $25 per station, per game, per year, and you had to do all of their games, then you still had to buy the games. So a center that has 40 PCs would need to pay blizzard every year $3,000. Your support that they promised was non-existent, and the only benefit you got was your website was put in their game center section, which no one went to. The program is still around but, Blizzard does not support it and you most likely will never get a call back or a follow-up email from them.
As I see it there are 2 options for game centers when it comes to licensing, join I-games and buy the license through them, or don’t be licensed. I can tell you as a matter of fact no game center in North America has ever been sued by a publisher for commercial use of software.
