Gaming Union writes: "At the Montreal International Game Summit, Jason Holtman, the director of business development from Valve, spoke in a conference about how the online distribution service of Steam has worked over the last couple of years, and sent a warning to the rest of the industry of how change is required to suit an ever demanding public.
One of the main points that Holtman argued is that an open marketing strategy with a lot of experimentation is crucial to maintain sales. Holtman showed a number examples from Team Fortress 2 and how Valve has continued to maintain sales for more than two years."
