Good question! My regular opponents and I do a few things that are a bit off from the book. They are mostly just courtesies that we feel like nice people should extend to each other, since we're all here to have fun.
1- You don't crash on a Turn 1 "To The Deck" roll. Just because it's a really sad way to start a game!
2- If it could have the skimming bonus, it does. We greatly dislike the "haha you didn't say the magic words" experience, so this addresses that particular instance.
3- Models are not within an inch of a building unless they need to be. We used to always say "...and it's not within an inch of the building..." after every freaking move that might look even 1.5" away from a building and we got tired of that. Also after too many "haha, gotcha!" feel-bad moments that were often hotly contested as to where the center point of a model should actually be when the model didn't need to be close to a building... we decided to play it this way. Of course there are times when things need to be close to a building and we call it as such.
