So, I've been curious about RPGs for a while, but I'm not really sure where to start at. I know D&D is the original and the de facto standard, but I also know there are plenty of others (I alreay have an Arcana Unleashed reference book that I bought ages ago because I thought the spells in it were pwn), but I'm not really familiar with them or their comparative merits. Can anyone with experience shed some light for me?
