I plan on updating the OP to discuss Wave 3 by the end of the week. In the meantime, like with Wave 1, I'd like to share the current banners here for posterity. As you all know, I hid two cameos in each banner, dedicating space to the top posters of this thread with their favorite characters.
For
Banner 1, I decided to focus on myself, since I was the top poster in the thread. Using New York Minute as the background and taking the banner that would have Mario on it already, I decided to make cameos based on the other ST's I wrote this year. Thus, we have
PAC-MAN to represent PAC-MAN MUSEUM + and
Classic Tails to represent Sonic Origins.
Banner 2, depicting Sky-High Sundae, features
Marx from Kirby to represent
@MondoMega and
Iroha Tamaki from Puella Magi Madoka to represent
@xghost777.
Banner 3, depicting Sydney Sprint features
the avatar of
@Skipper93653 and
Nenji Ogata from 13 Sentinels: Aegis Rim to represent
@Thunder84.
Lastly,
Banner 4, depicting Waluigi Pinball, features
Taki Tachibana from Your Name to represent
@Magic-Man and
Classic Sonic to represent
@totofogo.
Thank you to everyone who has posted in this thread in 2022! Looking forward to Wave 3 (and a few new banner cameos following a different, potentially more obvious theme) - let's hope for some great races on the new tracks!
