Old edition rules

So my friend isn't using the newest edition of 40k rules he is using the one that came in the battle for macragge. Is this going to impact gameplay much?(he is teaching himself these rules not the current ones)

Thanks,
Lance


Also he says he doesn't use the new rules because he doesn't want to spend $60 for 1 new rule and a new picture

The mini rule book is $20. Also, in 5 months he's going to spend $75 on a bunch of new rules.

Short answer, yes it will impact the way he learns the rules.

Long answer is that the basics of the game are the same, but detailed rules about vehicles, and close combat work will be different. To be honest if he doesn't want to spend 60 on the 5th ed book, he has the option of going on ebay and picking up the Assault on Black Reach Rule book, which is usually 20 bucks.

Edit: As Capn said, we're in a new edition year so be ready for only a big rule book rulebook update sometime this year.
