[QUOTE="Mark Hope, post: 8040842, member: 27051"] Yes, they are largely compatible - mainly when it comes to using adventures. Although the core mechanical chassis of the rules is largely the same, there are enough differences so that, for example, you can't really use a Basic D&D fighter alongside a 2e weapon specialist and expect them to perform the same. And there are lots of differences like that. There's a definite power curve from OD&D to late-era 2e - the latter is closer to early 3e in what characters can do, particularly when you're adding in S&P material. However, if you're familiar enough with the material, it's easy to pick up an adventure or supplement from any TSR edition and use it with another. You may need to adjust hit points or damage output, for example, or some other edition-specific rules material (morale checks or thief skills or clerics or whatever) but it's quite possible. My 2e-hack is doing this at the moment, actually, mixing stuff from several editions all at once. I play in a 5e game but don't run it so I can't speak to that, and I only played a bit of 4e. I converted stuff to 3e quite a bit (primarily Dark Sun) and found that it did need quite a bit of work - particularly as 3e grew in scope, the characters are far more powerful. One thing that I have noticed, however, is that it's very easy to convert backwards from 3e/PF to AD&D, particularly the 2e hack that I'm using. I don't need to use all a monster's various powers and feats and whatnot, but I can get an attack bonus and use hit points and basic damage ratings more or less as-is (minus bonuses for very high stats and whatnot). I wasn't sure it would work but I've been eyeballing it pretty successfully. Specifically, the Pathfinder version of Rappan Athuk has run very well in my hacked 2e game. [/QUOTE]
