Sixty-eight people responded to the question (a great turn-out!): “In a solo mod, what is your ideal NWN2 party size?”. And the results were:

Two results of special note: no one likes to play solo, and a larger proportion of players like to have 3 companions to adventure with.
Sure seems like the folks at OEI got it right in SoZ with their party of 4 player-created characters, doesn’t it.
Trinity is built around a party of 5 and you start off with the full roster of 4 companions. While players will be able to dismiss any of them at any point in the game without breaking conversations or quests, the mod will be balanced for the complete party and a good part of the banter and interjections will rely on all party members being present. My recommendation then will be to play with all companions, on a first run-through at least.
If I were to do it again, I’d probably go with 3 companions. But now, I’ve grown too attached to each of them and can’t see myself cutting anyone from the roster.
