I'm actually burning midnight oil right now to tank my way through Fran's route. It's less mad passion and more stubbornness.
OKAY if there is something that ruins my opinion of Baldr Sky Zero forever, it's the fact that it's literally IMPOSSIBLE to beat Kou in Fran's route. At about 10% health he stops taking damage, invulnerability from the get go would have spared me 3 hours of trying to make a combo out of the incoherent tech tree and doing practice runs to beat him but nooooo apparently Kou has Avalon from F/SN and is now invincible whenever it suits him. And who shoved a rod up his ass? Mercenary Kou is colder towards other people, but not a straight up asshole.. I want to believe in Baldr Sky Zero: 2, I really do.
On another note I found Baldr Sky X satisfying, the mercenary Kou story was particularly good (the others were okay) and there was quite a few extras with to keep myself briefly entertained. Though the coin system was a dirty gimmick to prolong gameplay and the main story was pretty poor.
Try looking backwards for older VNs that have passed under the popularity radar.
