I’m well aware of the mythical man month. If you have limited resources and only a couple developers, maybe you can only work on a shopping cart or cloud saves. It’s true that throwing at 10x developers at it isn’t going to get it done 10x faster. But if you have the resources, you can have a small team working on cloud saves while another team is working on, I don’t know, a shopping cart. Or designers coming up with standards to make store pages more useful.
I’m assuming Epic’s glacial slowness in rolling out improvements is due to lack of resource commitment to it, but I fully accept it may just be ineptitude and inability of their developers working on the store that more resources simply can’t fix.
