I'm sure this has been discussed before but which do you prefer? I'm sure GREE likes the collect 25 better since it has a leader board and people compete and spend more money. But for the normal free person, or light gold spender, the collect 10 is much better! Let's compare this crate event and the last one: Now for collecting 25 Cobra gemstones you get a nice 1350/1120 helicopter. For collecting 7 maps last crate event you get a 1120/1000 ship. Now compare those two different items with nearly the same stats. For one you have to collect 18 more than the other just for 350 more combined stats but one would be much cheaper. Now what if you come in the top 250 in this event though; you get a 2544/2930 ship. Compared to the last event, the 9th prize was weaker but most likely, much easier on you pocket. Finally, the 10th item last event was an amazing 8300/6536 plane which would also be a cheaper and stronger version of the top 50 prize this event. Just my opinion though. Who knows, you may like the collect 25 for the competition on the leaderboard
