So I would like to either advertise or sponsor my game. The problem is that I don’t know which one to do and how much to spend.
you could throw \infty money at an ad campaign and still not get good results, there’s no definite answer for either of these questions
put a little money and see how a test run goes, study when/where to advertise for your type of game and targeted age range, there are lots of resources on devforums talking about this. Also consider going off-platform to TikTok.
In my opinion… a small campaign run should be R$2500-R$10000, less than that and it’s a fart in the wind, outbid by larger campaigns for the same adspace.
