Brazilian portuguese is different than Portugal's one: there are a few
orthographic differences, and but the major changes are at the verbal
tenses: composite tenses give a sensation of the lack of action, with
doesn't sound good for a game with lots of action ;)
While here, fix a small typo at the portuguese (Pt) translation).
