no, I do no think they are talking too slowaly. I think  that "after" they are talking too much funny. As if Galaxy Masters have just smoken something weird  

Shweet!! Woo-hoo!

Arilou --  very sweet. I liked it.
Druuge -- great! keeps all the Druuge spirit
Melnorme -- good. Especially cool was these coin machine sounds
Slylandro home -- a bit funny, er, to say -- *happy* music. I liked it.
Slylandro probe -- great. Techno, spacy, drumsy.
Spathi -- good. Too fast as imho and i would like it to resemble old one a bit more.

Orbit II -- well done!
Orbit III -- cool! very *exploring* and futuristic
QuasiSpace -- man, it is a symphony! Simply amasing!
HyperSpace -- Eh.. Where is heroism??  It must be epic saga, not disco!

Thank you very much for your work, guys.

Well, when I saw SC2 first time the first thing I asked - is there Russian version? When my English got better I did not need it anymore.

Obviously, the translator must be very talented writer to keep all of F&P spirit in the game. There are jokes, cultural references etc.

And this job should not be done by more than two persons -- the thanslation must have style or not exist at all IMHO
