I surprised Timeshadows in the comments section for my post Why B/X is My Favorite #9 with a comment I made about 2E AD&D. While I am constantly surprised anyone reads my mental vomit here and since things seem quiet in the blog-o-verse, I feel like taking a quick break from why B/X is my favorite to look at why I prefer 2E to 1E AD&D.
While B/X is likely 98% to 99% the same as OD&D, I very much prefer B/X in part because it is much better organized and far more clearly written.
Welcome to reason #1 why I prefer 2E to 1E AD&D.
1. 2E, especially if you are not using many of the optional rules, is very clearly written and simple to understand.
2. It is compatible with all of the previous editions.
3. I am cool with THACO.
4. While I am very anti-splat book, there are numerous options available for those whose preference lean in that direction.
5. Specialist magic-users.
6. Nostalgia - I ran a very successful run with the Temple of Elemental Evil using 2E.
While B/X and 2E are very, very similar, to me they are very different games. I don't know if it is the way they are written or maybe the different play experiences I had with each version but, while B/X is a "game" to me (and one I love), 2E is a "roleplaying game" or nearly a "story game". And I believe there is nothing wrong with a story game so long as the players can have an impact on the story. I have even looked at Burning Wheel and while I found it very interesting and some of the mechanics quite provocative it is too rules heavy for me. Given my love of the reaction roll mechanic in B/X, it shouldn't surprise anyone to know that I don't mind social conflict resolution mechanics - so long as they are simple.
Today my true preference is rules-light games. The extent of the B/X or Savage Worlds rules are about my limit. Even the "basic" rules of 2E stretch my limit a bit. If I were to play a 2E-style game now I would use Castles & Crusades.
