Investing in Games: Broad or Deep?

Your hypothetical "startup industry" doesn't make sense because they're not tied together with respect to products. But there is a "tech industry" or "software industry" or "web tech industry" where the constituent players actually are related by product/service sector.
I don't see why you find that the most important thing that needs to be established. Why does it matter and how is it negatively affecting those (or any) businesses to refer to the games industry as such?
I think game development, publishing, services, esports, conventions and such are enough of a mature ecosystem to be considered it's own "industry."
As to games it's not broken down in the same way. For example some commercially generated games may be advertising for other products or even training tools so lumping those in with Call of Duty is pointless. Thus, rather than focusing on how their produced people break things out based on how their used and who pays for them.
Other investors I've run into also seem quite specialized. A bunch focus on mobile games. One that I've had second-hand contact with invests only in simulation games sold in boxed copies in Germany (this is a surprisingly large market). And then the console market is a whole other kettle of fish, because the console makers themselves have a pitch and funding process, which changes the dynamics a bit.
I think an industry exists when there's large-scale production associated with predictable returns. Like say the car industry.
In terms of marketing, it's my understanding that two metrics really matter on the success-side: engagement and the gold-standard - participation. Motivating players to buy the game is one thing, however - I think platforms that have inbuilt participation by design - really create a lot of free and ongoing marketing value (e.g. Minecraft, iOS, Little Big Planet etc.) Content creators have to promote the platform in lock-step with their own content. In my opinion, inbuilt participation mechanisms make things so much easier in terms of marketing. You can switch from "I've created something cool" to "look at the cool stuff others have made." Shared aspiration is very powerful.
Interestingly, this concept is something that anyone in the dot com, web 2.0, or whatever we're calling the tech scene these days knows. It's almost like the game industry is an island separated from mainstream startup tech (or perhaps I don't read enough).
What do you guys/gals think?
