As for wide appeal: flOw, Flower, and Journey were all developed to have wide appeal. Part of the core development philosophy of TGC is to make games that can be appreciated by a very large group of people. Both casual and hardcore gamers, and we've certainly achieved that.

Every step in Journey was, "How can make sure as many people have this same feeling as possible?" It most certainly was not, "How can we ensure that only a small amount of pre-exposed people will understand what we're doing?"

We are striving to be something like the Pixar of gaming, where we can make amazing titles that touch people of all ages, from around the world. It's hard to do this on just one platform. (You can be safe to know that we won't make something like Cars 2 just to sell merchandise.)
