To me, it looks like iT and GC are both just document sharing/video conferencing programs, for which some of the features have had their names changed to sound more like it's for gamers, and a boss can be assigned. They feel sterile and office-app-esk. FG, however, feels more like it was built from the very start to be for games and gamers.

I've played with iT and FG both now (I didn't even DL GC after I looked at the features list and screenshots. It looks like an unfinished version of iT, and even admits that many of its best features haven't been implemented yet), and here's my summary:

The FG tools are more intuitive and work the way I want them to, like the mask that lets me work by assigning what the players can see, instead of what they cannot and the grid tool that lets me create a grid layer on any map to represent distances and scale on the fly without having to import and resize an image file of a grid.

The material and programming that is included with FG fits the rules-set we plan to use; it includes d20 player's guides, class guides, and monster manual and it lets me use that info dynamically (for example, there is a D&D combat record sheet that comes preprogrammed to allow me to drag a monster or character record onto the list, and it will fill in the stats for me).

Then there are little Extras like the ability to hide dice roles, drag numbers from place to place and have the table understand why I'm putting them there (for example, once I have that combat record up, I can drag your init roll from where you rolled it onto the sheet, and it knows what that means), the area effect tools that allow drawing of circles and cones, and are smart enough to shade the grid to show you exactly which squares would be effected by the area drawn, and a short-cut bar that makes it easy for me to assign repeated tasks to function keys.

Finally, though least importantly, the eye-candy is sweet. Rolling dice is done by picking up virtual dice, and rolling them on the virtual table, rather than having to type out the specs for the roll, and have it simply return a number from an RND function. The program has a nice polish to it, including a full-screen mode that eliminates all menus and bars, 'Blank' pages have a parchment background, and as the DM, I can set the 'lighting' of the table to represent the location.


All these cool things I just mentioned about FG: iT doesn't do any of them, and the only thing that GC seems to do right is allow hidden die rolls.

However, iT isn't completely devoid of advantages. It is free, which is nice, and it has voice/video chat (with the ability to single people out for messages easily (which, I admit, would be really nice to have)) but this is not enough to outweigh the features of FG.

I'll work with whichever proggy the group decides to go with, of course, but consider this my strong recommendation in favor of Fantasy Grounds.
