Eighteen heroes won't satisfy anyone expecting the enormous roster of the original, and a fan remake deserves to be judged on its own terms. Still, there's something rather charming about seeing Dota 2 reimagined for a phone. It reminds me of the nights when everyone blamed everyone else, nobody wanted to admit they were tired, and one final match somehow became three. I wouldn't mistake this for the full PC experience, but the affection behind the project is easy to understand.
