Make a list of the different companies that sponsor Flash games. Research the business operations of each of these companies. Compile business information about these companies. Include when available their financial statements, annual revenues, annual net income, number of employees, Flash game distribution channels, their average payout per game, their credit rating, the extent of their Web traffic and information about their management that handles Flash game distribution. Also include the location of each company's headquarters and offices, their marketing and sales agreements, their licensing agreements, their patent and copyright portfolios, and any lawsuits related to their business operations.
Make a list of the terms that each of these companies require the developer to adhere to. Include any and all terms that must be fulfilled for the length of the agreement. Note if the sponsorship is a non-exclusive or exclusive agreement (where all rights to distribute the game are retained by the sponsor).
Make a list of the types of Flash games that each of the companies sponsors. Review the games that they typically sponsor. Also list any technical requirements that your Flash game must meet with each company. These often include a file size limit, a standardized game size (in pixels), a game preloader, limits on accessing server side PHP programs and databases, and links within the game that direct game players to the main website of the game sponsor.
Make a list of the payments that can be expected from each sponsor for the specific type of game you are interested in submitting.
Estimate the maximum return on investment of each sponsorship over a given period of time from information the sponsorship provides and what other developers have reported. Estimate the probability of the maximum return on investment (ROI) occurring for each sponsorship. Now, estimate the minimum ROI and probability factor for the minimum ROI. Examine the ROI probability lists, evaluate the possible scenarios for each sponsorship and determine which has the best risk/reward ratio for your present and future financial situation. Consider short-term and long term risk/reward ratios and how a specific sponsorship might promote or jeopardize other products and services you now offer (or in the future might offer).
Print out the agreement terms that each sponsor requires that you sign. Consult with an attorney that specializes in copyright law, intellectual property and licensing agreements about the agreement terms.
Instruct your attorney to send a letter of inquiry to the companies that you are interested in working with, or use standardized game submission forms on the websites of these companies.
