Goblin Campaign as a new DM

[DarkxInitiative]

So we're making character sheets on Friday 2 have never played and 1 has played 1/4 of a campaign(3 sessions) but they have all played AD&D second edition a lot the father whom played 3 sessions before is saying to take things easy on them but I'm skeptical should I just put them in combat automatically so that they can learn the ropes (since they know RPing pretty well) and is lvl 3 a good starting point?

Level 3 is absolutely fine for new players with experience from other RPGs. I like to do a hypothetical combat scenario against a CR appropriate group of enemies to give new players a tutorial and a feeling for what their characters can do.

This has nothing to do with homebrew though, so I will flag the thread to be moved to Advice.

Pathfinder is quite a bit more detailed and tactical than AD&D, so be prepared for combat to be slow at first.

Level 3 is good - better HP and therefore survivability. I'd also recommend going full HP rather than random HP. Let's characters be a little more heroic!

Combat is okay, but also be sure that that's what everyone wants. There's going to be a lot to learn for them all. Level 3 should be a good start. That will give any caster access to 2nd level spells and there will be some other neat things available to other classes too. Be sure to explain how things work as they create their characters. Encourage them to ask questions about the system.
