At least the name is clearly describing the product... can't say that from all the other engines, apart from the word 'engine'. If other so called "important" people have a problem with the engine name rather than your game... maybe you should find people who judge the looks of your game, rather than the engine name .

If the gamer crowd (who totaly do not care at all about whatever engine it is made) is happy with your game, surely the publishers don't mind the engine's name either. If they think your game sucks, they'll use every argument they can find to convince other people. That may include "roflol it's made with '3D kiddy game studio' =D", but those people are the last you should listen to .

The world doesn't think that bad about 3dgs at all:
