Ive been searching around this forum for a while and see a lot of ANN threads here. But Im very interested what ICOs and projects really achieved great results. Saying "successful" I don't mean these projects that just going to launch ICO. I mean projects that have already collected money and released product.
For example, this blockchain game. They collected good money and now its one of the most popular blockchain game. Here you can read an interview with its developer

And what projects do you know?
I guess another factor to be one of the successful ICO is to have a working product, particulary those that are pertaining to energy saving and efficient energy consumption projects that will surely help everyone.
