Q1: Are you willing to tolerate armour clipping with the exotic biology of some species?
Some clipping is acceptable, particularly with the helmet.
Q2: Are non-human faces an issue for you, particularly in cutscenes?
Absolutely not. A face does NOT have to look human or near-human for me to identify with it. In fact, when all the races look too close to human, that is a big pet peeve for me in MMORPG's. In WoW, I play a Worgen (Werewolf race), and it does not negatively impact my ability to identify with my character at all.
Q3: Would you be willing to listen to a non-Basic speaking species?
No. They would have to speak Basic.
Q4: Would you like to see gameplay options available to unlock new species?
Sure, why not?
Q5: How important is it to you that a new species in tied in to setting and story?
Moderate. I'd like to see story tie-in, but it's not a complete make-or-break for me.
Q6: Would you be open to species that cannot utilize either some or any existing armour, visually?
Depends on the severity. If there are a few minor cuts, like how boots only affect the ankles for Trolls and Worgen in WoW, I'd be fine with that.
My main problem with BW's post is that it implies that the player character has to look human or near-human in order for the player to identify with him/her, which is just plain stupid. If you look at major non-BW properties, you can see plenty of examples. In WoW, there are plenty of completely non-human looking races, such as Trolls, Tauren, Worgen, and Pandaren. In Skyrim (And other Elder Scrolls games), you can roll a Khajit or an Argonian. In WildStar, you can roll Mordesh, Draken, or Chua. Players are able to identify with these races with no trouble. That said, all those races listed above are able to speak English (Basic). IMO, that is far more important that looking like a human or near-human.
