Like any other gaming group, ours has a few house rules that we play by. When I was first reading through the 4th Edition Dungeons & Dragons books, it occurred to me that leveling characters would be a little slower than I would like it to be. The reason for this is largely due to my style of playing (as in not a lot of hardcore hack and slash). So I made up a couple of rules to help the player characters level up a bit faster.
Part of this is also to a) involve the players beyond showing up and rolling dice every other weekend and b) to introduce an element of competition. Let me start with the latter.
