The previous hanafuda screen (post #1144532) and the text on this one make me wonder if Gainax hadn't been planning more games at the time.

The vocabulary here is very close to the シンジと愉快な仲間たち (Shinji to Yukai na Nakamatachi) / Shinji and Good Friends series of games Gainax released after Evangelion blew up and featured among other things, a Hanafuda game as well as other Gainax characters including those from Nadia.
