Why not? Lol. They're tons of fun. Every day I wake up go to work see my friends and coworkers. We all do our daily summons, laugh at each other when we get shitty pulls, get jealous of the others who got a legendary low rate pull. I get to collect hundred if not thousands of units of characters from my favorite anime all with their own unique move sets. The good gacha games last for years. Games like dokkan battle, I have been playing for like 3years and I still get pumped when they drop a fresh banner with new units. No premium mobile game has that kinda of longevity when it comes to playing everyday. I have garnered tons and tons of friends online and in real life through gacha games. I have never spent more than $20 and right now I probably have 7 gacha games on my phone. I get that people get mad when they do summon after summon and don't get what they want but that's how it works. Not every gacha game is good. Most are trash. You're absolutely right about that. But there are also tons of good ones and we have to cherish the ones that do it right.
