Considering the shows in question and the studios behind them, I honestly think Re:Zero will fall into a "Devil is a part timer" level of forgotten. On the back of everyone's mind, fully expecting a season 2, but potentially never getting one. I think the No Game No Life example is apt to a degree but i feel like that show was more of a "don't expect it, but want it. OH its been a while, i don't care anymore" levels of sequel want.
I also think that No Game didn't really have anything that felt like it really stuck when I was done with it. Some cool stuff, sure, but nothing really overtly memorable. Re:Zero on the other hand, I feel, will stick with me for quite a while. Hell episode 15's direction, cinematography, and sheer visceral emotional roller-coaster has still stayed with me, months later. I mean, other than maybe the weird and kinda dumb word game with the library angle scene and maybe the Human Speech scene in No Game, nothing was really stands out.
She's not a midget though... but i get what you're trying to say.
