I guess it's going to be added in a patch that is yet to come.
While poking around in the game's menus (to tired to race after all those
***y exams -> 1.22 at interlagos, now that sucks!!!) I didn't see the
option to have a wet race for the "quick race".
Then I decided to check the g2.exe (some 5.7 MBytes) to see if there is
option for the language (german translation isn't that bad - but "heisse
Runde" for a hotlap - naaahh!). No luck - everything is German (the
version of my copy is 1.00b, BTW). BUT !!! Guess what I found:
"Nasses Wetter / Sie muessen mit einem nassen Rennen rechnen / Nasses
Renen / Wollen Sie Ihre Fahrzeug-Einstellungen aendern?"
which rougly translates to:
"Wet weather / A wet race is to be expected / Wet Race / Do you wish to
change the car setup?"
So I think there are two possibilites. Either wet races only happen in a
championship season - or they will be "activated" by a patch yet to come,
just like modem play was to be added to GP1 later on (God, I was exited
when I got that disk from Microprose - me & friends used to play on
386/33's in those days!).
Anyway - the game is great & I'm even more of a backmarker in the wet -
so no hurry!
Happy racing, David
