Just a few quick ideas before I get to the marketing part…
1: Can the left click menu appear instantly instead of fading in?
2: Can we eventually decide how much to sell each individual game for?
Now for the marketing system thoughts…
Each campaign could have different aspects to it that you could choose from - Magazine interviews, commercials on TV (Which channels? Which ones fit your target audience demographic?), web advertising (Which websites?) and the type of game and number of fans the series has (Yes let’s separate fans between your studio and each game franchise) could determine its effectiveness,
Would you get more impressions advertising your space game in a sci fi magazine, or a general hobbyist magazine? Which magazine caters to more of your demographic vs. how much does it actually sell? Each PR outlet should also have its own rating within the industry. For example, you want to have an interview with a journalist? Which web site then do you choose? You want to go with GameZoom.com or something, but maybe they aren’t being looked at favorably by the industry right now due to some scandal as to how they treated one of their journalists, so while they are promising you the most coverage for your interview, maybe in reality you wont get as much exposure because fans right now aren’t reading them and “boycotting” them.
You can see how far the rabbit hole can go with this, but I think the marketing aspect of this game has HUGE potential, almost like a mini game in itself. After all, marketing in the real world is indeed a huge part of your product’s success, and making a product a success is what this game is all about.
