Ok, thanks for the correction. How about if we say that Survival and similar skills will default at -4 to other planets of the same type as per the rules (because there are going to be new, different, and WEIRD plants and animals even on a different planet of the same type), but the -4 penalty can be 'worked off' as the character gains more familiarity with a specific planet. (Say at the rate of a reduction of 1 in the penalty for each week spent using the skill?) This will cause more bookkeeping, but it may be worth the extra time and effort?
And who knows where Spider and Jimmy have got off to! Spider may be on his way to the ship now, but there's NO tellin' where that sorry, sloppy drunk Jimmy will end up.
