I was wondering which d20 works would be most affected by the 3.5 revision, and which, if any, would be difficult to use.
I assume Ranger, Bard, and Sorceror classbooks are the most affected. Is there anything else?
Sorcerer? Sorcerer hasn't changed, except for being able to swap spells. Druids and monks have changed a lot more, but the essence of them is similar enough that Druid/monk splatbooks still pretty much apply. Heck, bard splatbooks pretty much still apply, too -- while the bard has changed, he isn't that different mechanically (flipping through Quintessential Bard, for example, I can make most of it work with 3.5 with little to no effort).
Ranger splatbooks. Gnome splatbooks -- the ones that refer to illusionists (poor Badaxe!). I'd say that's it for significant changes.
Minor changes: Skill names. Spells. PrCs. Adventures -- need to tweak monsters with DR, and some NPC statblocks (though if you didn't, who'd know?) although adventures with minimal statblocks have an advantage here when they just say "see MM/CRIII".
Since so many d20 products put out new mechanics, much of it probably isn't directly impacted in a major way (at least, looking at my d20 collection). Some things should be looked at slightly different for game balance -- spells in particular. Anything with prestige classes will need a little rework of pre-requisites, but that's pretty easy to do (some class abilities become redundant, though). But by and large, I think minor tweaks that could be done on the fly are all that is required for for most d20 products out there.
I'm sure others will disagree about what "minor" and "major" changes entail. It all depends on how anal you are about compliance.
Edit: Overall as a class of product, adventures are most affected (stat blocks, changed monsters, monsters who change CR), but then that's also where you can have the most inaccuracy. If you have a 3.0 monster in amongst 3.5, or a 3.0 ranger NPC instead of a 3.5, or an NPC with 2 ranks in Intuit Direction, will it affect game play? As an anal-retentive DM, I'd like all my stat blocks to be perfect, but if they're not it's not like most players would notice, much less care.
