In the current game - none of the above...
It's a strange low magic 2e/3e crossbreed, with no clerics or mages in the party, just rogues, fighters and and a ranger. Two of the PCs are a swashbuckling fighter with Wis 7 and a rogue with Wis 5 (and Int 7). Any attempt to construct and then follow a sensible tactical plan (e.g. party order) founders on the impatience and vanity of the fighter and the chronic brain-cramp of the rogue. They'll just rush on ahead whatever. A typical exploratory situation now goes something like this:
DM: "Ahead you see a huge, finely worked stone door. Projecting from the wall next to it is a slightly rusty iron lever..."
Swashbuckler & Rogue (in unison): "I pull it!"
Everyone Else: "We run away!"
Mad as a bag of ferrets.
