It's safe to say the only reason it is 4 is because dos2 had 4, and to do anything else means changing the system, hence extra work.
How hard can it be to put just one more character in and make it five?
Not looking at the game balance in particular but whenever I imagined any kind of fantasy adventurer group, dungeon goers or whatever, I always imagined five people. Always.
Six feels a little on the weighty side.
Four feels like one of them got cold feet and ran off.
Was it really just only four as well in OriginalSimp2? ^_^
I didn't even remember.
All I remember was that Archers were super OP with their highground bonusses.
