...okay, not really, but as it turns out, I do have a few house rules for my online B/X game:
1. Player characters do not start off knowing their alignment tongue.This is mainly because I haven't decided if I want to "repurpose" the concept for use in my campaign... on one hand, I think that a shadowy tongue used by the forces of Chaos is kind of a cool idea. On the other hand, I think it's silly for anyone of the appropriate alignment to just "know" the alignment tongue, magically forgetting it if they change alignments. We'll see. For now, ignored.
2. Max hit points at first level. Normal hit points are rolled every following level until name level. Fighters and dwarves can re-roll 1's on their new hit dice.
I'm considering doing something with the fighter's attack progression... yes, they progress faster in terms of level, but clerics and thieves tend to level faster, resulting in a potential negation of the thing that fighters are supposed to be best at. I might allow them to drop their to-hit numbers by one every other level instead of every three.... so their number to hit AC 0 is 19 at levels 1-20, 18 at 3-4, etc. I'm on the fence about this one.
...interestingly enough, in Raggi's Weird Fantasy rules, fighters are the only class that ever improve in combat ability; clerics, thieves, and magic-users are all frozen at their first level attack tables. (Actually, I think he calls thieves "specialists," but you get the idea.) I'm not sure I'd go to that extreme, but it is certainly something to consider.
