Still learning the software, it is comprehensive.
It comes with a set of tutorials, which teach you the basics of the program.
There is a good online FAQ at: http://pub19.bravenet.com/faq/show.php?catid=2776&usernum=1607948311
Just messing around with the program, after running the tutorials a couple of times, is really helpful.
You can add your PCs and Monsters to the software.
We're actually running a Gestalt game at the moment, so I've been using the class editor (copy the more complex class, and then edit in the features of the other class) to create Gestalt versions of what my players are using.
Monsters can be made as PCs (Villains) but anything in the SRD is included with DM Genie, and you can input your own things too.
Groups is the method of organizing.
Each encounter, is a group, which I've added the monsters to.
So I can navigate to that group (drop down menu), and then add the PC Party to the mix, and start a battle.
You can automate most of it, probably everything... but you can also have player input, where they give you their D20 roll and the system calculates the bonuses for whatever, say initiative.
Alternatively, they can give you their modified roll and you can input that instead.
I'm leaning towards the players giving me their D20 roll, having the DM Genie do all of the rolls from my end, and then having it track all the appropriate modifiers.
If your character is encumbered, it will auto adjust everything that extra weight affects.
You can add Conditions quite easily... just check boxes, basically... and it adds everything in for you.
So, we can go 'Invisible', 'Medium Load', and 'Fatigued' and it add everything up correctly.
I'm still figuring out the software, but it is definitely much faster in play.
And prep time is cut down too, as anything that appears in the books (SRD, anyway) can be added with a few clicks.
There are a few Yahoo Groups, with shared content (two of the three I found, have approved my membership... still waiting on the 3rd, which is likely inactive).
The files are zipped, with a password that is typically along these lines: 'Four word in column two on page 39', which basically proves you own the book.
Quite a few of the non-SRD books have had their details entered into a given users DM Genie, and then exported.
You can import what others have exported, as well as exporting your own material.
If I could give it more than five stars, I would.
Definitely worth the $25 license; plus you can try it free for a couple of months first.
