No problem. Just trying to be honest!
As you've mentioned, 50m for pennant box yes if you bought tickets from NPC
If you play an event games it would cost around 5m but its for you to find out what game and again enjoy the event .
I personally saving for the gun and the snowmobile . if im correct there is no entrance pay for the gun game and snowmobile race . then you enjoy the rest
cheers!!
