As it stands, having achievements for only like 100 balloons shot is way to less and can be achieved in a single event. Having variants of 500 and 1000 will be in no way bad and there is no reason for them to not be there. The count could be reduced for things like plane wars as 1000 will be alot for that (also snowball battle maybe). But they should atleast be there for fruit frenzy, target practise, balloon shoot, pumpkin smash and ghost shoot.
