I'm not sure this is entirely accurate though. I agree with you that it's widely believed, but just look at how many copies of Skyrim have been sold on Steam. There's a massive audience that could run a TES MMO with visuals on par with Skyrim. Dozens of player characters on screen might harm frame rates in populated areas like cities, but that's where smart culling and LOD systems come into play in MMOs. The further away a character is, the lower resolution his textures and meshes.
This need to go for a performance-friendly and cartoony look doesn't add up to me. Especially when it goes against the established visual theme of a series.
Well they were planning on having 100 VS 100 raids or something. I cant imagine that being untaxing on performance. I hear that SWTOR had performance problems because they used an incomplete and self tweaked version of the Hero Engine.
But as you said, you don't think the cartoon style is less taxing. I am honestly not sure either. I would think it is less taxing though. Anyone got any evidence?
Anyways, the style is not blatantly high fantasy cartoony. At least not as bad as most MMOs out there, or for my own personal taste. Most of that stuff doesn't bother me personally though. I play JRPGs sometimes lol. Not too worried about ridiculousness in the graphics. I just want the lore and overall look to not scream non-TES. That would be good enough for me. Accurate Lore that is not stretched so much it gets hypertension and certainly no lore that is just outright broken. I AM a hardcoe TES fan who's primary interest will be the Lore though. And having football pad armors with 9 foot swords would be stretching that lore too. I just like the art and feel like it is not that bad.
