Also, unlike Versus, they aren't teasing us for years on end. Atlus did not promise P5 would be the immediate game they would work on in whatever time they were asked. Considering how much portable games they've made during this, also Catherine, all this considering Atlus doesn't have the amount of spare money other japanese developers have.
Not to mention, even if their games are not "the best" graphics, at least their games are polished and they tend to please most fans, unlike square and their polarizing games ( FFXIII, FFXIV, DQX).
If I take Strange Journey which I've had tons of gripes with, still managed to entertain me quite a lot. For those who liked it, I bet it is much better.
