@gpowerf I don't know Roblox server management. #Minecraft, specifically #spigotmc has permissions control and various ways to set up how it behaves, but you should go with what you are familiar with. My objection to using Roblox is "I've never played it, and I know nothing to *admin* it." Which should be *YOUR* response to using Minecraft/ Spigot.
That said, you also have the option to use http://opensimulator.org/wiki/Main_Page on a server you control. It *really* depends on what your goal is. If it's *just* "icebreaker", and your team is relatively small, Minecraft Realms would allow you to set up a specific server with specific games for a low cost and easy management. They would provide actual game worlds you could all tackle together.
If the goal is more "virtual workspace/ meeting place," OpenSim might be better suited, but I'm not sure how serious *I* would be taken, as I'd show up as a tiny ferret.
And remember, anything not explicitly forbidden is compulsory.
@gpowerf I'd be happy to answer questions concerning #Minecraft if that makes sense. Minecraft Realms allows you to set up a "disposable server" on the cheap: You don't manage what you don't need to, they offer tons of "game world maps" with everything ready to go, just enjoy. There are certain limitations you would need to be aware of depending on your use case. I have no clue if Robox offers similar, and again, you should go with what you *know*. If it does offer similar to MC Realms, I'd suggest you go with that. But I'm happy to help with MC if needed. :)
@Romaq thanks. Very useful.
