Yes 3d is much more appealing!
Well, to be honest, I can't really tell you how much longer a game would take. I'm a slow player in the physical world and I don't play that much. When me and my brother get together to play a physical 3000pt game it can take from 3 to 5 hours! This was a solution I found so I could play more, and thus far I've only played once. We were going to play yesterday, but my kids sabotaged the attempt.
At any given time, there are 4 to 5 rooms with 40k games going on, so, it's definitely feasible.
As for movement, yes, you can drag a selection box across multiple items to select them all, or you can pick them one by one and add to a selection (Ctrl+click). The measuring tool can take some getting used to but is very practical once you get the hang of it.
Dice can be rolled next to a model instead of some place "far" away. This is particularly useful with the select tool, as you can roll multiple dice with different target numbers all at the same time (to hit or save for particular units).
As for Templates, yes they are the correct size, I made them specifically for epic.
The physics engine is dimensionless, so, 1 unit can mean whatever you want, cm, inches, etc.
This game works (Tabletop Simulator) by providing a physics engine based on a room where people connect to. All content is provided by users (and doesn't need to be publicly available on the steam workshop) via public download sites (dropbox for instance). Also, only one person needs to have have the links to the files, when you connect to his room, all the stuff he has in the room will be downloaded to your computer. So long as 1 person has the files and links you're good to go.
As for the units and armies still missing, yes, I plan on adding them, however, if the models need to ripped, it takes a lot longer. An army that has models already available, can take about 8 hours of work to make (and look good). This typically takes me a week to do.
What would help was to have a list of all the missing stuff for the existing armies, that way, work could be focused and goal orientated. As for missing (main) armies, we're only missing Tau and Necrons (both of these have already available models for 40k. The other person working on this is working (or will be working) on Tau. I'm currently working on Warmaster.
What would REALLY help, would be to have someone else join the band wagon!
