Why don't you want 50 girls? You know the only thing I can think of that would be better than 50 girls? 100 girls! Why would you want an end to this? If you do want it to end, then STOP PLAYING.
If I hear one more person on this thread say "feature creep", I'm going to lose it. It's like you don't understand what this is. It ISN'T REALLY A GAME! It's a bunch of GREAT art and GREAT animations, and an interactive way to unlock it and view it. Saying he should finish one character before moving on to the next is just ridiculous. It's like saying that an artist should paint every single picture that he might ever want to paint of one subject before he moves on to the next one. Seriously, THINK about what you're saying before you say it. Do you really want him to get to a point where he might consider the game to be finished, and thus stop creating more content? I certainly don't.
He will get to all the characters. He has gone back to many of the originals already. Batgirl was one of the original three, and two updates ago he went back and made a ton of amazing content for her. I get it, some of you want your favorite character to get content. I know that I have often wished that he would abandon everything else and just do Power Girl (Galatea for you kids out there) content until the end of time. But I want him to do it when he really wants to do it so that it will be as great as the rest. And every time he adds a new character, I think to myself, "well, now SR7 signed himself up for another few months of generating content. That's great!" I never want this game to be done. I want new content every couple months FOREVER.
Again, remember, this is NOT a game in the true sense of the word. It's click on buttons until you find new content. Just keep on doing that, and enjoying what you see. And please, for the love of all that's holy, do NOT keep pestering and insulting the creator. Unless you want him to say "screw you guys" and quit. I, for one, don't want that.
