[Feature Request] Sandbox

Whilst this game is very logical, sometimes the specialist abilities can get confusing.
A (single player) 'Sandbox' mode where you can spawn whatever you want, wherever you want, then assign them teams and get them to attack each other would be a great learning tool.
Any time you go 'I wonder what happens when...' could be put to the test immediately.
