Hi! I'm new to Pathfinder and about to run Gallows of Madness with just 3 players. I've understood that most modules are meant to be played with four players so this might be bit of a challenge to them. The module has information for how to scale the adventures for 2nd level characters which is handy. So here's my two questions:
1. Should I make any changes or can adventure 1 be played as is at level 1 and adventure two at level two? Or should I make any changes further on?
2. As the xp-progression will be faster with only three players it seems they will end up at level 3 just in time for the third and last adventure in this mini-campaign. Can a party of three play this at level three, even if it's meant for level 2, party of four?
I'd be grateful for any help!
The biggest thing to remember is that three players lack the extra actions of a fourth player - this may be the biggest detriment in various encounters.
Overall, I find most modules are just as "fun" and easily run if the PCs are one level higher than the published recommendation. If you start the PCs off at second level, you'll probably find the module runs smoothly. If you run the module with the levels as printed, be prepared for the party to need to adjust, retreat, or approach fights in careful fashion.
