Hey, me and my friends are new to the whole roleplaying scene and upon doing some research I found out that the best game to start with is probably Dungeons and Dragons. So I decided to buy the new Red Box online and have (attempted) to play a couple of times with my friends and we are all enjoying it, but Im starting to wonder what we should be buying next. I have seen that there a couple of different variants of Dungeons and Dragons and am wondering what we as complete newbs should be looking for. I cant tell if we should invest in the original 4th edition books, the essentials line or even go for the newly reprinted AD&D books. Any advice would be greatly appreciated and as a side note, Im also unsure of what exactly me and my friends should buy, what books are neccesary to get and, as money is a problem, what books are needed just to play the game?
