Yes, in (American) English, they're the same. It may depend on the sport which term sounds more natural: you play a basketball game, a tennis match, a game of checkers, a chess match, a baseball game, a soccer match. But if you said "The game starts in an hour" talking about soccer, it would be perfectly natural. For some reason though, "The match starts in an hour" talking about baseball sounds weird.
I think the translation using "departure" should not be in this module, because in Portuguese when we talk about soccer, we use the word "partida" to reffer to the game. Departure is more used in the aviation, travels. The Duolingo should use the word "match" in this case. Sorry, for my English. I am Brazilian native and I am starting learning English.
Hi! I have a question about the pronunciation of nasal vowels. So, I understand that an "m" or an "n" at the end of a word or before a consonant will make the previous vowel nasal, but I am a little confused when there is a nasal vowel just before another word starting with a vowel. For example: "em uma" (is the "em" nasal or is it pronounced like "emm").
