Blizzard declined, but a few years later Valve hired IceFrog to make Dota 2. IceFrog eventually went to Blizzard, asking to be hired to develop DOTA into its own game. But millions of people were playing the game, organizing tournaments, giving suggestions and even donate to fund development. At the time IceFrog was just 20, building DOTA with a volunteer group of staff. That network more than anything, allowed allowed DOTA to go viral. It even included online gaming capabilities that allowed anyone who owned Warcraft 3 to host and play a map that they had downloaded, effectively giving modders an instant distribution network. It included a visual programming language, a map building tool and thousands of unit and building models. But the power and ease of use of an out-of-the-box editor like Warcraft III and others offered last decade is something largely missing these days. Lots of games, such as The Elder Scrolls V: Skyrim, Crusader Kings, and Mount & Blade, still allow modding to some extent or another.
