Polish is a Slavic language and Latin letters are not suitable for it. I'm Russian who speaks English and a bit French and I can understand some Polish words (common roots etc.) like dobrze, dzień dobry, wiedzieć, znać, but I have no idea how to write them (looked up this words in Google Translate).

P.S. And I like to play Witcher III with Polish voices and Russian subtitles.

Most Slavic languages use Latin as primary script. Polish took a few questionable decisions compared to other western/southern Slavic languages (not switching from sz/cz to s^/c^ for example), but it's almost fully phonetic and pretty consistent. I'd argue Polish pronunciation is easier to learn than Russian, because we have no movable stress (we always stress the penultimate syllable - easy).
