The Elder Scrolls Online beta that #2 Son is doing is pretty cool. The challenge for Bethesda was to take their enormously successful Elder Scrolls franchise (Skyrim most recently, but Oblivion before that) and put it into an online, massively multi-player format. The results show a great protection of their franchise - it looks, well, it looks like Skyrim. The graphics are great, and the NPC interactions look like they should. The question is what the Player Character interaction will be.
Interestingly, #2 Son is always on his headset, yakking with his online buddies while he plays. My suspicion is that Bethesda will want to coopt this, to get the players off of Skype and put real time voice into the game. If you say something, people within "hearing distance" should hear you, and be able to reply.
Quite frankly, this is just VOIP (Voice over IP), and is a well understood technology. I'd think it would add to the game play, but that's just me.
