Reading around a bit, happened to pop into the Japanese Fallout 3/NV screenshot/mod database I mention sometimes.
Saw a picture posted. It was a group of the kiddie-companions those people seem to be so big on (and I'll avoid the urge to troll you all and mention something about the quake/tsunami being a divine punishment for loli/shotacon on a society-wide scale...). It is of a massive group. The title?
Twenty. Four. Companions.
This, boys and girls, is why us companion system modders get the urge to drink so often. Thankfully, no one's tried to take NCCS that far (or if they have, I haven't had to hear about it yet); but I remember more than a few RR players who were personally insulted that my mod didn't re-make the game engine so that they could have a party of twenty at a time.
I can't even imagine how hard that is on a PC that's even top-tier. Getting two dozen NPCs in one cell at one time is a frame-rate murderer at the best of times; but when they're all decked out in custom gear, high-poly meshes and high-res textures... and of course to make up for that kind of party you need MMM's increased-increased spawns...
And to think, I've always found four companions at once to be over the top.
