IF you love CRPG, honestly, you should learn English or Spanish. BG2 is not in PT-BR, nor Gothic 1/2/3, nor Icewind Dale, Nor Temple of elemental Evil, nor Pathfinder Kingmaker(...) You are missing a lot of amazing games.
That is really inconsiderate of you; You do realize that some people have difficulty learning their primary language, let alone a secondary language. Also outside of learning by immersion, learning additional languages as an adult (if you aren't already bi-lingual) is even more difficult.
