Tasks are important because they promote natural acquisition and internalisation of language similar to native speakers.
Games mostly promote rote learning and learning things by heart which doesn't lead to being able to use the language naturally, but games can be useful to help build the vocabulary necessary to carry out tasks effectively.
That's where language learning sites like duolingo fall down, for me anyway;
You say that as if there are these two things and nothing else, and you're contrasting "activeness" with "rote", which is too narrow a perspective. (And you're also suggesting that task-based activities aren't games.)
Tasks are useful if and when they promote meaningful engagement with the language, but rote vs meaningful is not "digital", there's a spectrum, and most tasks aren't 100% meaningful. If the task is "get X" when I say "hurdi-gurdi-hurdi-gurdi X", there is
some meaningfulness in the task, but I don't know whether hurdi-gurdi-hurdi-gurdi is a polite request, an absolute order, or anything in between.
In the end, such a long phrase would be memorised by rote, and there would be little variation in the language.
And that's the key word in language learning: variation. If you use a language feature in one way only, you learn it by rote. To learn it meaningfully, you need to learn it in various forms and circumstances, understanding how it influences the meaning.
Duolingo are kind of close to the right path on this. They have a reasonable level of variation -- in fact, in the languages that use text-to-speech for voices, they have potentially unlimited variation. Unfortunately, I think they've let their data lead them astray. They've no doubt spotted that people get more right answers if they repeat the same example phrases, and therefore concluded that they're "learning" better. No, all they've proven is that their teaching wasn't good enough to beat rote in the short-to-medium term.
(I believe DuoLingo's problem is their reluctance to explicitly present the rules, relying instead on learners intuiting them. But you can only intuit from variation, and if variation isn't working for your students and you're forced to fall back on rote, this means that intuiting rules doesn't work.)
