Well, again, these hypotheses can be tested. The engine is already set up for a six person party -- you only need to change a single variable to run six . The code is already part of the engine complete with party formation, place on the UI for the additional NPCs, three NPC banters ect
I found 6 party combat to be more fun because I do more things in combat and I was able to win without DOS tactics. Leave those barrels where they belong -- in Rivelon.
Yes, sometimes the toons did not have a place to stand right away and this led to some comic dances but this really underscores an issue people want to be fixed anyway -- problems with party management. Yes, 6 members made the flaws of the party management system more noticeable. But fixing that would be good for everyone.
The only times I've felt that combat was too long with either 4 or 6 person parties was when the AI took forever to have enemies "plotting their next move". And, again, combat was actually over quicker with a 6 person party.
Try it yourself and see which seems more fun. For me 6 is closer to BG feel.
Does this 6 person mod also increase the number of enemies in encounters???
I could see combat happening faster with a 6 person party ONLY if the encounter enemies are made individually tougher. If you just get 50% more enemies, then I'm skeptical it will significantly speed things up.
