An idea can’t be patented, but your app or game certainly can.
Until you have a tangible product, you can’t protect it. If you aren’t sure if you have a totally unique concept, you could always do an initial search yourself and then move forward with having a skilled patent attorney do a more complete search.
There are different types of patents.
A utility patent protects how a product is used and works.
A Design patent protects how the product looks.
As far as whether or not it’s “worth it” depends on your level of commitment. You can either let the idea die and do nothing with it, or you can develop and patent it in order to protect your concept from competitors. Keep in mind, even if the concept already exists, you could still enter the marketplace as a competitor if your product has something unique to offer.
