Both articles (Dave Grossman and Andrew Goulding) were very interesting reads.
Accessibility is a huge issue for more casual-orientated games but as we know, these games with a lower barrier of entry have been
growing more and more complex over the years, blurring the line between "casual" and in this case, "adventure".
I certainly don't believe that this amalgamation should be a cause for concern amongst adventure game enthusiasts. Telltale aren't just going to stop making adventure games in favour of hidden-object games. Personally, I think this deeper understanding of what new players need in a game can only be seen as a positive.
