That's the Digger comic.
It's in book form, too, but that costs more money than I really have to spare, so the free web version is what I go back to.
(It's a complete and finished story, not ongoing. And be aware that although you will certainly laugh, there are a few moments when I ended up crying, too. So there's that.)
RPs with two people is very hard, you only have one player and the DM so it's hard to get that creative gestalt going. RPs with three people is actually my favorite, or four people if some of you are often tired or not quite such high output people.... five people and now you have to deal with interpersonal politics too much for my taste, and it slows things down because you have to check every change with every person, and blah.
I know someone who is trying to run a group of seven people.
SEVEN.
He says that every week at LEAST one person is missing, usually two, so it's mostly that he likes redundancy in the group, but there are times when everyone is there and then you have to deal with seven people! Well, six plus yourself.
That's crazy!
