Put me in the group of, "VTT isn't good enough, yet." Otherwise, our face to face group would continue to play that way, and then supplement with online play. It's still too much like using MS Word, circa 1990. You can write documents with it, but it is often too much hassle for what you get, unless that is your only good option (e.g. repeat template letter).
Part of this is that we don't have any true 3rd generation VTT products yet. You know, the ones where it had all the features it could possibly need in version 2. So in version 3, they perfected the user interface and made it foolproof.
Another part is the same "translation" problem that early MMORPG and CRPG games had, compared to table top. Ideally, a VTT product would be for a game system written specifically to be played online, with a game master. Then the mechanical side of it would flow more naturally, and the social features would be pushed to the max. Many of the VTT products right now are really:
1. A way to do virtual table top where you take away the table and use the computer--and in fact sometimes well enough that people use it for that when they are all sitting around the same table.
2. A lot of social features (e.g. chat, voice, etc.) to let you use this while you aren't all sitting around the same table.
You'll note that #1 is not necessarily the best way to focus if you want to maximize mechanical play when people aren't sitting around the same table, but makes a lot of sense for transitional products.
For all that I write software, I'm not an early adopter. We are still in the early adopter period for VTT--albeit rapidly closing in on the 2nd generation products. Give it time.
