> Not sure how you'd enshrine price limits into law, though; that seems impractical.

Thinking in childrens' terms:

• Any microtransaction <$1 is fine, up to 10 per week or 20 per month or whatever

• Anything between $1-$10 should be more limited

• Anything $10 or above should be limited to 1 per week

• No microtransaction should cost more than 50% of the game's own full price, if the game isn't free
