I know VS forum CMS is a bit _whatever_ at times, but it is possible to edit posts, you know!
A Monkey Island fight sequence wouldn't be so complicated. That would have been done by if else then queries & 2 values. If you got the question right or the other npc said the incorrect thing then you increment the enemies value by 1 else you would increment the value assigned to your character by 1 then you would check if value of player or enemy = a specific amount to determine if fight should continue or end & who the winner is.
I think what I've roughly described above should be enough to get you started in the right direction. There's pages in manual section of the wiki that explains about conditions & values, should you need a bit of information in regards to using/understanding what they are for &/or can be used for.
