Every gacha game is fun until you reach a point where you need to open up your wallet. If you don't care for character pulls, then a lot of gacha games ARE fun. You can just open it up for a few minutes and go on with your day.
You're safe if that's how you deal with F2P games. Others aren't.
what a surprise i started 4 days ago myself. my frist ever gacha game and it's not as bad as i thought. kinda annoying how you have to reroll the account to get the first few pulls and try to get the most meta characters..
