Is it legal to buy the license WHEN the game is finished? And how about payment, and such?
Cause im really looking forward to use this engine.

Sure, as long as you're not getting any profit from your application you can use the engine for free
You need the license only when you want to earn some money from the game.

Do you take visa electron?

I'll send you the info to a private message

Thanks... And im tired... Its 00:22 here in Denmark... I'll go to sleep soon...
