It was my hope that WotC would somehow position themselves close to the films in some fashion to bank on the resurgence of fantasy. Whether this has happened I can't say. However, there are some very good signs that over the last few years, and the years to come, a new influx of gamers may come from:
-computer console, and internet rpg's. Very, very popular right now and seem to be attracting a boat load of new blood.
-movies and television have been very fantasy/sci-fi orientated of late. Buffy is leading the charge, but stuff like Samurai Jack are great and then, of course, all the comic book films, etc.
-LotR and HP seem to be the biggest influence. LotR may reinvigorate those that haven't played in years and may want to get back into it, while HP is setting the stage for those becoming old enough to try it.
-however, the most encouraging sign I've seen is what is going on at the local Warhammer store. It's always packed, and not with the same faces every day. I was in there browsing over the weekend and kids where standing around the demo tables mesmerized. Adults were chatting with staff candidly about product. All makes and models of guys and girls were present - from the "geek" to the "chic". Now, I know what you're saying, "It's Warhammer, not D&D!", but I don't think that it matters. The point is, here we have a sizable portion of people with a wide demographic interested in table-top fantasy gaming. Let's hope they find D&D. And why shouldn't they? D&D begat Warhammer, the reverse could be true. I'm just pleased at the range of customers. Great potential.
Anyway, that's my thoughts on it. What D&D really needs is a quality film of its own that could rival LotR. We didn't get it, unfortunately, but because of the success of LotR, some talented director who knows what direction to take the film in is likely to be given a second chance. I would suspect that there was a surge in Spider-man product and comics after the success of the movie. D&D would do well to have another kick at the can.
Cheers!
