What concerns does the tabletop RPG industry have? I see three main issues currently affecting the industry.
1) Fewer retail stores. This affects both sales and player recruitment.
2) The format of presenting content is changing (consumers use less books in favor of online sites, PDFs and ebooks).
3) Increased competition from other entertainment platforms.
People on the enworld or RPGNet forums might complain that WotC is losing their edge in the RPG market to newer companies, but looking at the above issues, I see WotC actively trying to address them (to various levels of success) whereas other companies are not. Paizo has a leg up on PDF sales, but they’re not exactly going out of their way to address any of the other issues.
In fact, I once asked a panel of independent game publishers at a convention if they feel obligated to support local game shops and what programs or incentives they have in place to do so. To a man, they all said that it was not their concern and they don’t have, nor plan on creating, any program to entice customers to support retail shops.
I guess they didn’t share my concerns.
