I never looked at the Guinness site before this link was posted and was surprised by the number of "marathon" records posted which were little more than someone staying in front of a non-ending title such as "Minecraft" or an MMORPG title where you can hack-and-slash to your heart's content hitting 60 million boars in "Warcraft" just to get into Guinness. Half these so-called "marathon" records are jokes in comparison to, for example, a 2-day marathon at a title like "Robotron".
Wouldn't surprise me if Guinness was willing to track the longest consecutive time playing "Minesweeper" with no more than a 60-second break between games and a one hour break every 12 hours. Seems like for a "nominal fee" they will track any type of record nowadays.
There are records for the most number of people dressed up as (you name it...a smurf, Santa Clause, whatever) at the same time. All these people need to do is each bring a shopping bag filled with a fake rubber Donald Trump mask for ten bucks and set a second record for the most people wearing a Donald Trump mask at the same time...for another "nominal fee". It's a joke.
Millions of gamers across the decades, without even giving a passing thought to Guinness, played at one point or another a favourite RPG or MMORPG, or a newly released franchise title like "Mario 64" when it first came out, for anywhere from 1-3 days straight. These so-called "marathons" that Guinness tracks are not impressive at all....they are just testaments to whoever needed an ego boost and paid them their "nominal fee" for verification.
Honestly I don't know why someone would want to BE in Guinness anymore for video game records...not when they have the the following text on their site right at this very moment...
