This product is almost perfect.
The only thing I didn't like is when buying rulesets, beware that they may not get the attention of being updated (see my review of Iron Heroes for FG2).
But however, I did enjoy playing with other players and GM'ing that I did upgrade to an Ultimate license.
This utility hase everything you need to play a pen&paper game online, however you do need to buy supported rulesets to expand beyond 3.5srd
Playing with the addition of a voice chat client speeds up your game over Fantasy Grounds greatly.
The community of players is large, so the only problem is finding those who can attend at your prefered times. I have created a friendship with a dozen other players that play in my games consistently (all of them full license users) and I have hosted games for those who only have the demo version.
You will be surprised at how many Ultimate License holders host games so demo players can experience a "full" game experience.
