Funny, isn't, Wormwood, how other DMs just fail to match up to 'your' standards!
With D&D3, strangely I can't help thinking that it's the openness of the rules that gets to both DMs and Players. DMs like the openness, since it's relatively easy (if not always wise) to adjust things to produce a particular game flavour. Or what we imagine is a particular game flavour... until the full ramifications of our House Rules become clear and we realise we've made a boo-boo!
From the Player's perspective I find myself saying 'gimme back my rules-given choices!' It's easy to forgot Rule Zero when you can't choose the race you want, or the feat, or the Prestige Class, or get the equipment that your character concept 'absolutely needs'!
Oddly, much of the discussion I read of House Rules in 3e seems to relate to limiting options. Now I fully understand why, indeed the writers themselves recognised this by discussing how you can adjust the rules to recreate a 1e feel. But it's different to earlier editions, where most House Rules tend to be along the lines of adding extra options: e.g. removing or expanding racial level limits, altering multi-classing, adding new classes, etc. Of course the
Complete X series and then
Players Options did alter this somewhat, but the gist seems right, IMX.
Errmmmm... the trouble with posting late at night is you can't recall what your point is!

I guess I am saying that, yes, DMs tend to like House Rules a lot more than the Players do, and that 3e seems to breed a different general tenor of House Rule than maybe earlier editions did.
