I got this game recently called June’s Journey. It’s not as good as I hoped, tbh, and if I was playing it in English I’d have given up by now, but setting it to Portuguese settings turns out to be quite useful. A lot of the gameplay hinges in spotting items in a picture and clicking on them. Since the names of all the items are in Portuguese (Brazilian Portuguese, but hey…) it has turned out to be quite a good way of learning new vocabulary.
I have a couple of games that I play in Portuguese already, but this is the one that looks set to be the most beneficial.
