the majority of gacha don't go far enough so you're never truly dating the character you like, but they also omnipander so you get characters you couldn't care less about dickriding you in a pg way and it just feels awkward
plus, because they're releasing a new character every 3 weeks, your favorite will quite quickly fall to the wayside and you'll be lucky to see them in the story in the average year
and the writing always sucks compared to proper vns. oh whoa this cheery happy go lucky character has a tragic backstory, how original. you've padded out the story so well by repeating things a million times and we all know the mark of great storytelling is more words
also playing more than one gacha at a time is insane. go ahead and play one, but people who juggle dailies and events in multiple games need treatment
