I'm definitely an old-school gamer from the late 70s early 80s, and a nostalgic one at that. While I moved on from D&D a long time ago to explore different game systems, RuneQuest has always held a special place in my heart. Now called Mythras, this system is flexible yet crunchy, and allows for a wide variety of player and GM inventiveness and imagination.

Classic Fantasy satiates my nostalgia for the old days of fighting orcs and kobolds, whether in a dungeon or a town invasion, but updates it to the modern Mythras system. I've already pulled out some items for my current game, and will probably run a full Classic Fantasy game in the near future. This is a solid book, chock-full of goodies, and if you're not a D&D player, it makes access to that world very easy for you.

Another solid supplement from The Design Mechanism and highly recommended!
