@PapaPole @rohrkrepierer never spend money on mobile games. If the game feels like a grind, then it's not fun and you shouldn't be playing at all. If the gameplay is fun, then who cares? Just enjoy the game and enjoy what you get for free.
Will to make it to the top of the leaderboards as a free to play? Of course not. Will you have fun? Yeah, and that's all that matters.
@PapaPole @rohrkrepierer I used to play MOBA games and spent money on those, as well as TF2 back in the day, but I got my money's worth due to the hours I played them.
However, with freemium casual games like gatcha games, there isn't much to the gameplay to justify spending money. If you just want to unlock pictures of your waifu, just look them up online and download them.
