i see that all gems on gog.com seems to have only english language

but i've bought Flatout and it is multi5 language
so it have also italian language (i'm italian)

then why on the game details page i see only english language? (http://www.gog.com/en/gamecard/flatout)

it will be good if on the details is specified if there is other language on the game or if it is multi5 language etc..
then i can know if a game have italian language before buying it

is it possible?

(sorry for my bad english)

There's this. I don't know how up to date it is though.
