One strange part of the Super Mario Odyssey reveal trailer was the opening segment, where Mario travels to a city with human characters in it. He skillfully swings from lightposts and vaults between buildings. But what if he wasn’t so adept and the physics were more realistic? A silly video from YouTuber CrowbCat imagines what that would look like–and it’s a sight to behold.

“Mario discovers the real world but it isn’t as fun as he thought it’d be,” reads a line from the video’s description. Watch in horror (or amusement) in the video below as Mario navigates Grand Theft Auto IV‘s Liberty City and gets hit by a car, falls off a building, flies a helicopter, and visits a strip club. This being a GTA video, there is some choice language and partial nudity, so be aware of that.

CrowbCat used a number of GTA IV mods for this creation–you can see a rundown of them in the video’s description on YouTube.

Super Mario Odyssey’s NYC-like city is just one of the levels in the game. The reveal trailer showed that Mario will also travel desert- and forest-themed worlds, as well as a trippy-looking, polygonal world featuring sentient forks. The game launches this holiday for the Nintendo Switch.

According to Mario creator Shigeru Miyamoto, Super Mario Odyssey is on the “core side;” he likened the game in that respect to Super Mario 64 and Super Mario Sunshine and not the Super Mario Galaxy series, which he said was a more accessible extension of the series.
