I think some of the write-ups are unnecessarily negative, but there's certainly one thing that can't be denied: it's hard to see people attracted to professional sim racing series when a lot of what attracts them to real racing is the experience and the fact the drivers are doing unbelievably dangerous things at very high levels. Formula E loses a bit of atmosphere anyway with the whining cars but going to see them in person I guess you get the location, and even to some extent watching it on TV. Seeing a virtual location isn't quite the same, and a bunch of people sitting at PCs in their socks isn't terribly interesting either.
Ok, and the other thing that can't be denied: it's rather important to test systems you're going to use in a million dollar televised race. F1 was bad enough not thinking to try a new qualifying format using simulators to see how it actually played out (and nip it in the bud before it saw the light of day), but for a company organising a simulated race to not use some race simulations to test their systems beforehand is just crazy.
