Caterpillar

Here's my theory of game development as a target market: It's very hard to come up with completely new game concepts. Therefore most games will, at least in some ways, be similar to existing games, and thus appeal to the same audience.

To compete with existing games, a new game needs to differentiate. Most of the ways it could do that are production values that are going to tax the underlying technology. Any tools that target game development as a use case have to contend with that fact.

And any such tool that is new and underfunded (all of which applies to Caterpillar, at least right now) will have a hard time doing that. Which means it would initially be restricted to use cases that do not require much competition, locking it into a hobbyist audience. This can be a difficult position to be in.
