Just the one point? When running 3 man warbands it's never just 1 point for me, it's usually 3-6 points for surviving!!!

House Rules used:
You can ALWAYS Run, even if an enemy is within 8" (That big chap there 50 times bigger then me but behind that really tall building, I can hear him stuff approaching with care! Run away!!!).
You have 4 weapons slots not including the free dagger. This means a warrior can have up to 4 missile weapons (braces count as one) or four combat weapons plus the dagger or any combination therein. This allowed warbands without the missile weapon option to actually get much more flexibility. It also allows pistoliers to go through 4 separate braces of pistols (pistols, duelling pistols, double barrelled pistols, crossbow pistols, warplock pistols, have I missed any?). It adds alot of variety and fun.
Pistolier and quickshot can be combined together to allow a character with 2 braces of pistols to fire all four in a single shooting phase. We kept the old school feel here, always enjoyed it more. If you have hunter well damn but you can load fast!
Optional back of book rules aren't optional, they are considered part of the game.
Random Happenings happen every game turn even after one has occurred (5 Bloodletters on the field is nuts!).
Just a general rule of thumb: As much terrain and rubble on the board as possible, it's a ruined city after all. The most fun we've had was in a game where the most open piece of board was 2" by 1", also levels, it was about 5 levels high (levels being 2-3" high with or without buildings on them, many crossing over streets below to form tunnelled streets, blind alleys et al at several levels of the board...
There's a few more we play, can't recall them currently.

Cheers,
Luke.
