Hey guys,

In your opinion/experience, which of these is the better category and sub-category naming scheme, and why?:

- Online Games
- Downloadable Games

- Online
- Downloadable

In other words, is it better to "double up" or use "adjective only" in the sub-category name?

Please note that, in my case at least, only the top category will appear in the URL (permalink).

Thanks for any advice.
