As said before, the online section of Pulse lacks a few features.
One more thing i'd like to see is the display of every running game on the "join game" screen.
They could be grayed out with a few information such as remaining races for tournament games, so that we can decide to wait for a game to end or just join one already available.

I guess that would also give the feeling that there are many games running, because most of the time it looks quite empty, what is probably disappointing for newbies at least. The number of games is displayed on the country/language screen but it's not as user-friendly.
