The best comparison I can come up with is Too Kyo Games.
Too Kyo
Studio BB
Formed with 7 experienced members in 2017 Formed with 7 experienced members in 2019 Initial line-up of projects was 1 anime, 1 small game, 1 medium game, 1 big game, and 1 gacha franchise. Initial line-up of projects was 1 small game, 1 medium game, and 1 big game (the medium game is a remake) Took 3 years to release the small game, a smaller game that wasn't in the initial line-up of projects, and the anime. Took 3 years to release a trailer for the medium game Took 5 years to release the anime prologue of the gacha franchise. Took 5 years to develop the medium game mostly in silence about it. Took 6 years to release the medium game (it was pretty unpolished imo). Haven't taken 6 years yet.
