It takes some "pros" over 200 minutes to finish a game. And I thought an ARAM game that drags on for over 30 minutes is bad.
I'm not a DotA2 hater btw, but seriously, that's just crazy for being unable to finish a game in under 3 hours. What's the longest LCS game in LOL btw, under 2 hours right?
They were prob in a contest competing to see which team could get the most Roshan kill in 3 hours.
I'm not the most knowledgeable Dota 2 person, but I did watch it so here's what happened, but first some League and Dota terms just in case anybody that's reading it doesn't know.
Radiant: The "blue" side (lower-left) in League Dire: The "purple or red" side (upper-right) in League Barracks: Basically inhibitors, but they DO NOT respawn Ancient: Equivalent to the Nexus in League, destroy it to win Buyback: You can spend gold to revive yourself when dead, it has a cooldown of seven minutes
The Radiant team was pinned down in their base for the majority of the entire match with only one single Barrack along with their Ancient exposed. The Dire team tried multiple times to rush in and beat them in a teamfight, but every single time the Radiant would just buyback. The Radiant's team composition was also extremely good at defending and sometimes they wouldn't even need to buyback.
Since Barracks don't respawn, they could never safely leave their base without risk of a backdoor happening. How it ended was that the Radiant were lucky enough to catch a Dire player out of position alone near the Radiant's base. That Dire player's buyback was already on cooldown so they were able to take advantage of this and make a huge push to win.
My longest was 76 min. probably the funnest game i had. i was 
had a
