Here's an idea.
I could look at recent or unusual video games and talk about how they compare to older or more "standard" ones. That way I would have specific differences to focus on and wouldn't end up trying to sum up an entire video game in a single blog entry.
Of course, this has been done before, (see, for instance, Sequelitis) but I don't think it's been done all that often, and regardless, I think it can be rather useful.
First attempt to come.
