Just a couple of things about Harn:
A lot of people seem to be under the impression that Harn (i.e., the setting, HarnWorld) is intended for those who want "realism". I don't personally think that's true; Harn is very much a fantasy setting and it's well-suited to those who want to run a "fantasy" game. That said, Harn is more
consistent than many other fantasy settings that I've seen. By that, I simply mean that things in Harn make sense: its cultures, its history, the settlement patterns of its inhabitants, etc. -- all of this things are logical. That doesn't mean that they're realistic (although, insofar as Harn is based on medieval Britain, it is quite historically accurate); it just means that the authors have created a fantasy world in a logical way. For me, as a GM, this is great. It gives me a solid foundation upon which I can build my own extensions to the world. Furthermore, it makes for great roleplaying, because the consistency makes it much easier to suspend disbelief and really immerse yourself in the game.
Keep in mind that you don't have to use 100% of the material in Harnworld in order to enjoy it. When I first started using Harn (almost 20 years ago now, holy crap!), I think I used the map (which, by the way, is beautiful) and maybe 10% of the written material. The rest I ignored, because I didn't really need it for my game (high-fantasy 1st ed. AD&D) and because I hadn't had time to absorb it. So, don't feel that Harn is necessarily some huge commitment that's going to force you to radically change the way you play. There's tons of material that you can take or leave, or use as you see fit: there's plenty of inspiration, but what you do with it is up to you.
One thing I really enjoy is the Harn community. Yes, there are some vocal "hardcore" fans who can be initimidating, but by and large people are really open-minded. There are some very talented people creating free Harn-related material (much of which, incidentally, you can use whether you own Harn or not); Patrick's website (
http://www.swordsandshields.org) is one that I highly recommend. Personally, I'm lucky enough to be involved with a group that's creating electronic Harn products, including stuff based on Profantasy's Campaign Cartographer 2 software. Our website is at
http://www.thechmp.com if you're interested.
A quick word about HarnMaster (the rules). Personally, I love them. Yes, they fall into the "gritty" category, but that's fine for me and the people I play with. If you're not happy with your current rules, or if you want to try something different, I'd really encourage you to check out HarnMaster.
Anyway, thanks for listening, and good gaming.
