Last year I called Sword & Sorcery studios the D20 system "publisher to watch." So who, other than WotC, do you think will be the D20 system publisher to keep your eye on, with the most promising titles and product lines?
I think Sword & Sorcery are still the people to beat, they got out of the gate early they have lots of money and so far they quality products. Certainly they are not inassailable, but I suspect they will still be around when many D20 publishers are just distant memories.
I think it is not just S&S but Sword & Sorcery & Company
The fact that Sword and Sorcery helps out Malhavok, Necromancer, and Fiery Dragon means that when I think of any of those I think of the others - a happy little family.
I have to say I am going to be watching Eden Studios. Especially with their Fields of War coming up. I will also be looking forward to Privateer's two sourcebooks coming along, as well as Green Ronin's new classbook series...
