Nah, new game take top spot is not surprising. It usually last just a while if the game is not extremely solid. Although I always deem Kamihime to be the most formidable rival for FKG. As I expected from the game that take top spot in both DMM and Nutaku. Aigis is old but stay strong on DMM, it really surprising why Nutaku end the game. DMM pull plug as always? Or other reasons? No solid confirm from peeking into Aigis forum yet.
The rest usually clash for top 10 spot fiercely as ever. Raven girls, Idol warz, Rebless X, even the new game Goddess kiss seems hold its own well. But it's still pretty new game. No definite judge yet.

Hope for better deal this year, especially Christmas time. The free rainbow would be a real treat, but I can just hope.
