I'm a former SK player who came from Yohoho Puzzle Pirates and has since gone back to YPP. I still stop back every few months to read the forums and sometimes play for a very short while.

I suspect that players of each game see OOO unfairly favoring the other. Since SK added Missions, it is no longer easy to tell which game has more online players, but before then, it appeared that YPP had more. Of course, number of online players is not the same as total number of players, which isn't the same as total revenue. Still, my guess is outside the first 6-9 months after the initial release of SK, YPP has earned OOO more money, but that SK is far and away the second most sucessful game that OOO has released.

Based on the number of updates, and the significance of those updates, SK gets *WAY* more attention than YPP. In the last two years, YPP has gotten nothing but trivial releases, similar to the trivial releases SK has had for the last two months, but SK gets these trivial releases much more often. YPP has nothing compared to SKs changes to the arcade or energy. OOO is working on ipad/android tablet support for YPP, but the results have been horrible. The most noticeable effect of OOO's tablet support is that OOO is trying to push a tablet GUI onto desktop players. Since OOO doesn't want to implement new features on both the current desktop client and the tablet code, all improvements to the game have been done only on the tablet client. Since few people play the tablet client, these new features have been poorly tested and poorly thought out. And, to be clear, the new features that OOO has added to the tablet version of YPP have not been as significant as the changes that have been made to SK.

I don't play SK enough to know if the changes OOO has done here are well thought out and a big improvement, but SK clearly gets more attention.

Dunno how this is going to change with Nick leaving and OOO shutting down their Doctor Who game.
