Hi, from what I can see... great product I want to know...

1.) Are there any limitations or fine print to me building apps under the white label package and reselling for any price I choose, any way I choose.
2.) Do I owe you all any further payment after I sign up... I'm thinking about getting Tier 10 just to get it full access in one shot.
3.) Am I able to create video game apps, like those little "townspeople" games etc.
3b.) If so please provide a little detail, if not please let me know if there is anyway we can offer that.
4.) Is there ever a time that an app we build for a customer won't be acceptable to ios or driod... if so how do we remedy that?
