One of my co-workers mentioned an old PC game and said that it would be great if we (me and my colleague) could remake one for windows phone few days ago. But the project is too small for two programmers and both of us have enough skill to create this game.
Who should back off in this situation? If one of us was told before the other, it would be easy to decide but now I am confused.
Note: I'd love to work together but it seems that he does not want it.
And in general, how do you decide if it is worth it to continue working on a project when you know that another person works on the same thing and neither of you has any crucial advantage?
