TF2 and OW are two similar yet different games both in terms of their story and their gameplay, that's for sure.
I think the problem is just that people don't realize that getting inspired isn't not necessarily a bad thing, you just need to put your own spin on it and OW certainly did that IMO.
Great post ! Would you mind if I included it in today "best of gaming"?
