Ok, so this game seemed great at first glance. The whole concept of studying language while playing a videogame probably seems fantastic for every gamer like me, who also likes to broaden his knowledge everyday. However, Influent isn't what I expected it to be. I didn't do much research before buying, just a short review by someone who generally praised the game but mentioned lack of insight on japanese "kanji", which immediately put japanese pack off my to-buy list. Therefore for starters, I picked up french pack.
After a bit more than 1 hour of playtime, I can pretty much say that for me the game is a large disappointment. The whole game is situated in a small condo which contains about 400 different objects that you can interract with, and consequently learn more about them in order to improve your vocabulary. Those consist mostly out of basic household items.
In French, gender is of crucial importance, and although the game tells you which gender a certain object is, when you actually learn them, gender pronouns or indefinite articles are excluded from the actual word. For example instead of "une lampe" or "la lampe" you'll study "lampe", which means you'll still need to study gender separatly. Furthermore, the game doesn't cover one bit of grammar.
The game itself isn't particularly fun either, since one is as already mentioned, trapped inside a small condo. If the game would include also some other everyday areas like playground, trainstation, gym, school etc. it would vastly improve the vocabulary covered, but I'm afraid this will either never be available or will be purchasable as a "dlc", for which I honestly wouldn't waste a cent anymore since I don't consider the 400 foreign words to be worth of 10€, while you can learn them for free in (in a sense of content) much better covered "game" called Duolingo, or Anki.
Summary: I love the basic idea, but it lacks a lot of content. Although it is obviously considered as a supplement to your language studies, I still believe that it could've included a lot more than just bare 400 words.
