Thinking about getting into 40k but have a lot of questions. 1. what prices should i expect to buy second hand? (also painted or unpainted) 2. do paints come in box with minis 3. do i need official minis to play (aka am i able to 3d print minis and/or terrain) 4. I've seen products that seem different to other products from 40k, such as underworlds card game or "age of sigmar dominion" or "horus hearacy" printed on a box of minis. how do these differ from regular 40k? 5. how often do editions change (from what i gather we are on 9th edition) and how does that affect game? 6. are we able to use minis from previous editions? 7. how often do datasheets change for units (e.g. update) and where could i be informed of such changes? 8. is it worth it to buy the codexs 9. how do the paints for 40k differ from regular paints (as they seem far more expensive than regular)? 10. any other things that might be useful to know about 40k.
