Some questions on game concept, may be seeking help.

So I have been planning out quite a large and if I may say, a bit ambitious idea and have a few questions.

  1. Are there limitations to the overall size of a “scene” or level in Unity? Meaning, is there a way to have one very large (i.e 4 miles) land mass on which the game is played on, or must it be broken up?

  2. How difficult is it to establish a massive multi-player system for a Unity game? Not in the sense of grouping, raid mobs etc, but in buying and selling items and materials in a game, chat channels etc.

  3. Let’s say I had a free to play game but I wanted to sell items in the game for real money, how difficult is it to tie that kind of system into a game?

To try to keep answers short.
You can create an open world. Don’t know if it’s 4 miles per se but big is possible.
Multi player is possible. Nickolodeon, Cartoon Network and others have MMOs with tons of users and are based on Unity. Without going to look for other games, those are ones that are available.
There are a few solutions available for in app purchasing.

Of course this can be expanded on but this is the short answer.
