I haven’t been playing Z-A much, but I’ve now achieved A rank in all 14 seasons and have only 3 link play titles still to get:

Consummate Gamer — Nothing to Gold. Only achieved this once and I have to do it 49 more times!

Comeback Kid — Bronze to Gold. 8 more times to go.

Mega Rush Master — Nothing to Gold. Still need to get back to Rogue Megas at some point.
