Just because someone else may be doing the same character as you, who the heck cares? The whole point of mugen, or at least a major part of it is to be able to create your own version of something. If someone didn't believe that, then they should have no more than one Ryu and Kyo in their mugen roster at once, since they only support having one style of a character. Why do you think having character variations was such an awesome feature of MKX? Two people can both pick Scorpion, and it would seem like they didn't when you watch them fight each other. If you were to stop making a character just because someone else is making them too, it would only be because you would be scared of having your work or yourself be viewed as inferior in some way. Mugen is for fun and should stay that way. It may be for competitive fighting games, but Mugen itself isn't intended to be a competition. Just keep making whatever it is you're making, do your best, ask for support if you need it, and watch the magic happen. It would only be bad if two people were making the same character, at the same time, with the same bases, doing the same moves, same gameplay to the letter, and so on. Then yes, that would suck, and be pointless, and would inevitably have the 2 projects compared to one another due to the sheer similarity.
