Modding and possibilities

We know that StarControl will have extensive modding support. What isn't clear is what core concepts are supported "out of the box". Specifically things that aren't(?) needed for the StarControl campaign/story - but may be pivotal for custom games.

Can we get a word from the devs with respect to these concepts:

• XP gain / leveling
• Ability / skill selection (possibly tied to leveling)
• Slottable items / modules / upgrades for ships
• Individual pilots / "heroes" for ships
• Shopping
• Ability limit (2 abilities? 10 abilities?)
  
  
• Is everything in place to make a "tower defense" custom game?
• Is everything in place to make an "asteroids" custom game?
• Is everything in place to make a MOBA (DotA, League of Legends) custom game? 

It's okay to say "we don't know" to individual items; as long as you can also point out which items are currently supported/possible.
