If you ever wanted to learn russian, then this game is totally the best one to learn basic russian and insults at one place. Forget about school, get Dota and play with cold-blooded russians, which doesn't shrink back to insult you because you're not playing good with a hero, which is in their opinion, the easiest hero in the whole game. Well, the only thing is that you cannot understand them while they're talking ingame, because they're mainly talking russian.

Get yourself a dictionary and start learning russian there! It's the best thing you can do.

10/10 would play it again.
