I for one hate doing house-rules - for me a house-rule signifies either a percieved error in the rules or something I strongly disagree with. ...quote]
I know this is entirely a personal thing, so I'm not at all trying to be argumentative, just explain my own style.
I take completely the opposite view. I almost never run the same game twice with the same rules. Every time I set up a campaign, or even a one-off game, I very heavily customise the rules set I will use to the particular focus and style of game I want in that particular campaign, with those particular players and set of characters. I'm all about customising the rules and the setting to what I'm trying to achieve for that game.
The way I see it, the rules ina rulebook reflect the stylistic preferences of the author or the style of game it's aimed at creating. The chances that the particular goals of that author will allign with my needs at any given time is very low, IMHO, so I don't judge a game in this way.
For example I have a Traveller campaign I'm in the process of preparing for. I say 'Traveller' but actualy the character generation and game system will be based on Call of Cthulhu, but world generation and starship design will use modified Traveller rules and it's a home-grown setting. I'm using BRP partly because the Traveller careers aren't appropriate for the character backgrounds for this game, and because it's more familiar to more of the players than Traveller. If the players were all old Traveller hands and didn't know CoC I might have done things differently. Also even in this setting, for a game based on characters with more Travellery backgrounds I might run it using Traveller character generation and core game mechanics.
