If you make a creole, keep in mind that it will probably end up as SVO, isolating, and analytic no matter the parent languages. For instance, Chinuk Wawa's parents were the highly polysynthetic languages of the Pacific Northwest, but they gave birth to an isolating language.
I'm sure that's only if the superstrate ancestor is the language of one of the European imperial powers of 1500-2000.
Imagine a creole descended from a pidgin whose superstrate was a Celtic verb-initial language. It might indeed be isolating and/or analytic, but would it not probably be verb-initial?
Is Unserdeutsch (Rabaul Creole German) verb-medial or verb-final? Is it isolating? Is it analytic? Namibian Black German appears to be verb-final. I don't know about Belgranodeutsch.
You might also consider http://en.wikipedia.org/wiki/Michif_language
, which is a counter-example to more than one majority trend among creoles. For example, it had obviation, not a feature of French.
Creoles don't always simplify away any feature of one parent that's not shared by the other parent. For instance most English-based creoles in the SouthWest Pacific seem to have a dual number in addition to singular and plural, and to have an inclusive-vs-exclusive opposition in the nonsingular first-person pronouns. Some of them even have a trial number in their pronouns.
I bet that, if both the superstrate and the substrate parents of a creole were verb-final, it would usually be verb-final; and if both the superstrate and the substrate were verb-initial, the creole would probably also be verb-initial.
But, lingua franca
s don't always retain features shared by their parents. If both parents are tonal the lingua franca may not be. If both parents have large noun-class systems (say both parents are Bantu languages) the lingua franca may have a much-simplified noun-class system.
