Let's see if you can endure the first 20-30 episodes of KHR :>
It took me like 3 months to watch them, that's how boring they were.
Btw, khr is the same as DGM, the anime stops too early so you'll have to 'manga' :p
Edit:
As for steins;gate...
The first few episodes won't make sense, but you'll begin to understand later and it'll make perfect sense if you rewatch the first episode again after finishing it.
