To cut a long story short - I'm looking to get back into it with a few cow-orkers. Last time I played on a regular basis was LRB5. Realize we can pick any set of rules to go with, but I like to do things "real proper, like".
What do I need to pick up (or download) to have a complete set of current rules (including extras such as Dirty Tricks etc)? Do I need to replace any of my 3rd edition physical components (pitch, rulers etc?). What are the major changes to team lineups - is there any decent comparison between editions?
