I think you guys are thinking down the wrong line of "multi-media". It isn't just movies and TV.
1999 was before smartphones, tablets, and World of Warcraft.
You guys are way too focused on the random number I threw out there. Fellowship of the Ring opened on December 19, 2001, so yes, I should have said 12 years, 3 months, and 5 days. Apologies.
It's not about the types of media, it's about the timing of that media.
2) Game designers are, in general, a poor fit for writing novels, coding video games, making movies, handling licensing, or otherwise doing the whole "multimedia" thing.
Truer words never spoken. Writing is not an easily transferable skill. RPG writing is essentially technical writing with vignette fiction thrown in. There is nothing else like it in the world, that I am aware of. Maybe video game manuals. It certainly won't help with screenplays or game scripts and it obviously doesn't help with novel writing, much as it pains me to say so.
I think Hasbro understands that the tabletop game is the core of the brand, at least for now. If they didn't they wouldn't have waited for two years while the new edition was playtested.
To be fair though, Paizo has shown that you can go the adventure route.
Paizo goes all the routes. Their release schedule is unrelenting.
It's also worth noting that, per Dancey's old Escapist interview, a key part of WotC's motivation for doing the DDI was that they couldn't do a full-on MMO due to licensing reasons. Since those reasons no longer apply, and if they're now following their multi-platform path, doesn't that suggest that they're more likely to go for the full-on MMO rather than a new DDI?
I have so many opinions about this paragraph. Sigh. Here's the least angry one: D&D already has two perfectly serviceable MMOs, made by two of the most successful developers in the genre (which is not saying much), and the second one is actually a fun /game/ even if you hate multiplayer like I do. If they announce a third MMO, I might just have to fly out to Seattle myself and start slapping faces. The only people an MMO is good for are the shareholders.
Video game wise, D&D needs exactly what Shadowrun needs, and what the CRPG genre in general needs. Not an MMO, but an open world action RPG with five-player co-op, a nice long story, a robust system for procedurally generating random quests, and Steam Workshop support. Neverwinter comes /so close/. Another few months of development and it will be even better, but it will always have to deal with the MMO baggage, so it will never be perfect.
