This group is for you which want to show in your profile you are a single person developing a game, making if not all the game aspects(music, coding, arts), at least most of it, the famous 'lone wolfs' of the indie game world. This group also is supposed to show you respect greatly others which do the same, other 'lone wolfs'. Our games sure take longer to come out and demands much more effort, but you bet they are cool when they do!
That is what I thought about the subject, I may be wrong, right or partially right; maybe these thoughts can be usefull to one of you solo devs?
