Tower Defense Help

Hello! I'm currently making a TD and I would like to know what kind of things you would want in a good TD and other things like if a TD should be hard or really easy, a bank system, lottery, super powerful rigged races, or w/e you think should be in a good TD.

i personally think that tower defenses are getting old, and that there are tones of them out there. To make a good tower defence, it has to be exceptionally good. Personally i think its better if you think of a new type of map, or set a twist to it other than the traditional way.

Or if u want something good in a TD , invent something that the others TD dont have , so your map will be unique...
