Ann: ICI New Game Claw Stars Pre-Orders Exceeds 1 million, page-514

I would also say it doesn't necessarily matter if
a) The revenue is in the first 5 or 10 days is less than Masketeers
b) The ARPU is less

Both those things are helpful, but they're not necessary for the game to do well. If it's less that might be why they haven't made any announcements, but they're just two metrics. What matters, to me at least, is how the game performs over time, the size of the tail and active users. Since the launch of Masketeers was very successful it sets a high standard.

Like you could have Game B that launches with slightly less revenue than Game A. But just because it launches with less revenue it doesn't mean the tail of Game B is the same as Game A. Game B might be more steady and overtake Game A at 35 or 45 days. Not saying that would happen, but just an example.
