In regards to sales, I'm not helping it either because... 900 gems for 10k yen. 300 gems per ten-pull with the same "minimum guaranteed 3* character and a 4* roll". That's 3 ten-pulls, which is very small when you factor in how much you're spending. Yes, you can upgrade the 5* characters' Ougi without rolling and that's a major change from FGO's necessity to pull the gacha for NP upgrades (not that NP upgrades were ever important for the most parts) but when it comes down to spending money, the thought of that little amount of rolls will turn people off. And no safety net either. FGO doesn't have any safety net and we (the playerbase) are slaves to it but Sakura Revolution doesn't necessarily need to follow it.

Also, FGO is my primary spending location. Cash for FGO first, any spare might go to Sakura Revolution when they improve on their gem payouts.
