I am getting back into D&D after years away. I am teaching the game to my kids and the different 4E rules are making me a bit crazy. I'm sure there are previous posts on this but Iwanted to get a recent opinion on the different rule books. I started with the soft cover books like the compendiums and the new boxed sets. I just picked up the core players handbook and there are big differences...for example the half elf granted race power. What do you recommend? Which should I use for the players?
