No, your going at it backwards. Tim isnt working on multiple titles becasue he hired too many people and he needs to give them something to do. Tim has stated multiple times that he wanted a studio that worked on multiple titles simultaneously and he hired those people with that intention in mind. So its not a case of developing more games because you have such a big staff. Its a case of Tim hiring such a big staff to make multiple titles. That was his intention. Of course, if he changed his method and went to a single game studio, he could effectively fire 60% of his staff. Since this is exactly the kind of studio he wanted, I cant see that happening unless he hits serious financial problems.
As for calling what Tim does glorifed welfare, you cant honestly be serious? The best part about public funding is NOBODY has to give a single penny if they don't want to. People can give to their hearts content or they can walk away and never give Tim or his games a second thought. To suggest that is some sort of glorfied welfare is nothing short of ridiculous. As long as Tim delivers on the game side, there is absolutely NOTHING wrong with the funding methods he has used and quite frankly, Broken Age is hands down the best point and click adventure I have played since The Longest Journey and it would easily be in my top 5 adventure games of the last 10-15 years. So in my opinion, he is delivering. I gave 250 bucks to the Broken Age Kickstarter Campaign and I am not disappointed in the least.
