Since Kojima and Sakurai are two of the best trolls in game dev history, I've been wondering how trolly their game could be. How trolly do you think it will be?

I don't know.......very?

You buy the game and the case is empty level.

You put the game in your console, and it turns it into a mecha doomsday device.

I saw what Sakurai did with Sm4sh, so...

You'll buy $60 with $60 worth of free DLC.
You'll soon find out that all you got was the DLC, and you can't play the base game.

In two weeks, it is revealed that you had actually downloaded a new game where you engage in Tactical Espionage Operations, and that Smash is the $60 worth of DLC for the game.

At the end of the game, it is revealed that the player had actually functioned as Sakurai's mother, grandfather, and son. It is also revealed that Kojima has been captured by aliens and thus launches the first post-game campaign.

By the end of the second campaign, it is revealed that the one who was captured was actually Koji Kondo, which was the reason behind symphonic music stopping midway through the first campaign.
It is revealed that Kojima had pulled all the strings and you must now engage in a massive end-game sniper battle where if you fail, there is an unskippable 3-hour cutscene after a mandatory autosave. However, there this is only on your first try and succeeding tries don't have the autosave.

After you win, and the staff roll ends, it is revealed that you had actually hypnotized Kojima to do all this because you wanted to see the ultimate ruse cruise.

End.

Of course!
