Specifically NES Wrecking Crew? Or its predecessor Vs. Wrecking Crew?
There is never a bad excuse for me to chill for Famidaily, so if you want to dive in the Famicom Boom of 1985, here is the full playlist for the year in Family Computer software.
Anyway, if Criterion asked me, my vote would go to The Super Mario Bros. Game. But since Insert Credit is asking instead, I have to rep my boy and vote in Xanadu, first released on the PC-8801.
Now, I didn’t play the game in 1985, obviously. I discovered Xanadu via the Falcom Classics collection on the SegaSaturn in 1998, and I must admit I am specifically enamored with the remake of the game (called Saturn Mode) available in this version. The edges were smoothed just enough to maintain the oldschool charm of the original game, but tons of little quality of life improvements made it possible to enjoy the experience without banging my head too much against the walls of game design obsolescence.
The original is very rough by modern standards, but its influence and place on Japanese game design is obvious in the context of 1985, just after Druaga, Hydlide and Ultima III but before Zelda, Dragon Quest and Ys. It’s also, more importantly, the game that built Falcom as we know it! There is no Ys, no Sorcerian and no Sora no Kiseki without Xanadu. As a consequence, possibly no Koshiro Yūzo in video games and definitely no Quintet.
Here is a great overview of the original version that I have probably shared on Insert Credit already two or three times.
