Eternal game.
Not in terms of the second part, but in terms of Dota as a whole. Started at one time as a map for the third Warcraft, it quickly gained popularity and turned into a separate, albeit small, project. And after some time, it became so famous that Jewels with W3 were bought just for its sake (well, they were downloaded, too, of course).
Now, the creator of the original, having accepted the offer from Valve bosses, moved to a paid position from his post as an altruist and created a completely independent project with the number two.
This is a classic confrontation between two teams of five characters in the MOBA genre. Three directions, waves of creeps, towers, runes, Roshan and thrones - all the main elements migrated to the second part.
Naturally, not without changes, but they are still being made since the release of the beta - the balance is being finalized and corrected, experiments are being carried out, new heroes are being added. The game is still alive, despite the decreasing online presence from time to time.
