My marketplace assets have been downloaded/bought more than 1000 times in total! Most of my assets stand out by being very easy to use.
The best dialogue engine from my dialogue engines is "Dialogue engine - Text Boxes". I also recommend "Inventory engine". It's a fast and easy way to get a good inventory system for your game. Also, recently released "cutscene engine".
