I mean I guess hypothetically, if we ever manage to contact some aliens, and manage to establish friendly communications with them, cultural information is probably the easiest thing to trade (since information can be sent at light speed with relative ease whereas any mass takes much more energy to move much slower, since there probably aren't any material resources that are particularly unique between star systems to necessitate trade, and since whoever has more advanced technology might be a bit wary with sharing that particular information lest it be used against them if relations sour in the future), so it's not completely absurd to imagine us sending something like a video game that had come to be seen as a particularly important cultural work, to aliens, if we meet some at some point.
