So if I were going to run a 4e game on a VTT and want to use some automation tools, I'd probably go with Foundry. It has a 4e ruleset to handle the basic automation, but (from what I can tell) you'd need to add all the details as far as powers, monster stats, etc. But the core of the system is there. I think Roll20 can also do it to a point. Just depends on which UI you prefer, because neither is really built for it. Neither really has character creation options, but I think you could get together with the players on a board or Discord and figure that out.After posting this and getting some positive responses, I don't think I would have trouble finding a group. I'm certainly not a publisher by any stretch of the imagination (I'm game master, Jim! Not a writer!). My concern is being able to provide a suitable (and keep in mind I have high standards for myself) venue to run a 4e game online. I want to accommodate players as much as possible while making things as easy on me while I'm running games. I don't mind putting in the extra work, but I need the tools to let me do it.
Hope that makes a little more sense.
I can see if I can find anything that FG was using back in the day. Might still be out there somewhere...
