They are different games, but..
It is safe to say that out of the players who enjoy competitive strategy on pc at least 9/10 are playing starcraft 2. There are many reasons, including excellent marketing and historical greatness of the title "starcraft".(not dragged through the mud like "supreme commander")
There are many potential Supcom FA players among these players, who never heard of supreme commander, and those that have, have a firm belief that there isn't another RTS game that comes close to SC2.
Question: How do we reach these people? Think of ideas and post them here.
One possible tool suggested in chat:
An OBJECTIVE list of pro's and con's of each game. A list of things you can do in Supcom FA that you cannot do in starcraft, but always wanted. Also list advantages of starcraft over Supcom FA (actual gameplay, not just the fact that there are 500k starcraft players)
To do this will take players who have a good understanding of both games. Think about differences in unit control, resource generation, advancement through tech stages, types of resources, effect of time, etc.
If you feel like you are able to do this, reply in this thread with your thoughts. Based on how much information we are able to gather, perhaps we could create a video going through these differences.
