For some reason, the urge struck me about an hour ago to pull the old 2E DMG off the bookshelf and see what sort of rules it had for ocean travel/combat. I found a small section for travel, nothing for combat (was it in the PHB? Have to look later). I was wanting to see if there was anything I might port over for the Maritime Campaign if we get it off the ground.
I started flipping through the book after reading the small section I was looking for, and was reminded that there's a lot of good stuff in there. Sure, it lacks the simplicity of BX or BECM or the grandiose verbosity of Gygax in the 1E DMG. But there are some nice little tidbits to find within. [And the art wasn't quite as bad as I remember--better than the RC anyway.]
In particular, I'd forgotten that there are about 20 different types of Protection scrolls. I've always been a fan of them, and missed them during my 3E era. They provide cool effects, and are usable by any class. Scrolls don't become the 'dump on the M-U' item with them available.
Usually when I think of 2E I think of the rules bloat of the Complete this and that series. But the core books are solid, and deserve another look every now and then from those of us not playing them.
You never know what you might find that you can use in whatever other edition of the game you're playing.
