What makes online gaming great? The competitiveness and knowing the other player is real.
Thats why I love online racing games more than other games. You can compete head to head, wheel to wheel against a real person and personally I feel much more excitement and pressure in racing games than for example in shooting games. When Im having a tight, close race in lfs/iracing/whatever, absolutely nothing could beat it. When I play battlefield, it just doesnt feel as exciting.
What would I want to see in an online racing game?
Dunnolol, lfs styled online racing game is pretty perfect imo. Simple but still so good.
