I do think the success has made them take notice but the extra cost and complexity of designing a CRPG will turn off a lot of studios. The profit ratio for a CRPG is just gonna be lower. I am hopeful the smaller studios that have already shown some skill at this like Obsidian, Tactical Adventures, Owlcat Games, inXile Entertainment and Hairbrained Schemes will step more heavily into CRPG. They will have to temper expectations however as dealing with WotC will be a turn off for studios to seek out DnD liscencing.
Well, but that's the thing. For me, I DON'T want it to be a D&D game necessarily. I actually do not like D&D mechanics, and want someone out there to come up with something better. But because so many millions of gamers, and especially and specifically cRPG-ers, are so very wedded to D&D mechanics and often won;t even give something else a chance, any cRPG that is not D&D automatically takes a huge popularity hit. And that sucks for me, because I specifically want party-based fantasy-setting cRPGs that are NOT D&D.
Plus, I absolutely hate WotC and I want RPG developers to effectively tell WotC exactly where they can shove it.
