Heh, this is a little idea that's been bouncing around in my head since before 4e hit the shelves. I look at it like this:
- 4e was playtested by the RPGA
- Many of the changes done in late 3e were informed by RPGA play
- While I don't think 4e gets in the way of world building, it doesn't really help that much either - and since RPGA play doesn't require world building....
- The DDI VTT will be a huge draw for the RPGA
- Very exacting language
- Very concerned by class balance
- Ejecting races that were ... underplayed
- Including races that were more played (Hey, it's not a secret why the Iconics for Paizo's Age of Worms included a Tiefling)
- Expanded rules for covering role play experience awards
- Streamlining rules to allow easier DMing
There's likely more, but that's what I can think of right now.
So, to me, if 4e turns you off, it's likely because you weren't a target for RPGA play either. Or, rather, you don't play like people play in the RPGA. If you like 4e, likely your playstyles were more in keeping with how the RPGA functioned at the table.
Honestly, from a corporate standpoint, I think WOTC's idea is full of win. If they can hook just 10% of the RPGA into the DDI VTT, that's about 15000 players. That's a smidgeon under 3000 groups, or to put it another way, an RPGA game starting every 5 minutes 24/7. That's a massive draw for D&D. If this works, they've solved the issues with physically getting groups together. And they'll make a ton of money doing it as well.
