Comparisons like that don't necessarily mean one is better than the other, C2 is new to the game so judging by popular games being created in one or the other is an unfair comparison too. In about 10 years if we still see Fusion games getting famous on popular YouTube Let's Plays (eg: Five Nights At Freddy's) and not so much the C2 games, then maybe we could worry about Fusion becoming a better tool, but I switched from the old Clickteam products because Scirra makes the way-better interface.
Thanks for your concern. Actually I have been thinking same things as yours. People chose Clickteam over C2 because of the famous games. That is why how new developer starts from scratch, choosing the thing has successful example. Like people just choose Gamemaker because of some games.
My comparison was about having many reviews -> sold well -> richer -> can hire more people(?)
I guess it's not that simple.
