I do not prefer multiple games in a day myself. For OP, I'm not sure what worlds you play in, but I used to carry a team in all seven 1x worlds. A lot of times, recruiting overlaps, so that can add complexity. But when it happened, it was always an RS1 in one world and an RS2 in another. So that was helpful.
Anyways, what I liked about it, was that it was all done in succession. So once one world would end its NT, the next one would begin. Not sure if that would interest you or not. But I always liked it because the NT action never stopped, but it was never overwhelming either. I could always focus on one teams NT at a time.
Maybe it's not for you. But I wanted to throw that idea out there. Even if you don't do all 7, if you like more HD, there's more worlds and teams available
