I don't have any problems with spending money on gaming but I'm still careful with what I purchase. I tend to get a couple of newly released games every year and then I also have to spend a bit on my PlayStation Plus membership. In total, I probably spend around $250 a year on gaming purchases, although sometimes less if there aren't any good games out. I believe $250 is around 13,000 PHP.
1600 PHP is not much from what I have noticed. I have spent around 800$ for both phone and PC. I think my expenses are rising because I tend to play the in app game purchase. And it can be pretty difficult to keep up with the expenses. I know for sure that gaming takes some time and money. So expenses are expected.
I haven't spent even a peso at gaming, that is because I'm not actually a hard gamer, I don't actually take games super seriously, as if it is my life is depending on it. I see games the way it must be seen, for entertainment.
