Timotheos, I do not believe I am as important so that Playmobil will do anything I say. That kind of pedantry on my part would border stupidity. Just think that the more you ask to a person, the more likely is that the person we are talking about less attention pays. I think it most fruitful to ask for few things.
Not even in this case do I think they will do a line just because a person says them to. But if many people does, it is more probable... When we ask, we are just adding a bit more to that "many" (if it finally ends in a "many" after all). It is like when you vote, one by itself does almost nothing, just along with many other persons.
I wrote Playmobil back in 2001 for they to make a Roman line. I am not saying that because of me they made it, surely they heard many people interested (or looked many people was buying Roman-based toys).
