No need to be facetious!

Have you not noticed how much the price fluctuates? I've seen it down to $300 recently, which would drop the tiers to $300 and $1500 respectively. All it'll take is for another major world development and the bitcoins are suddenly worth nothing... but hey ho..

Game dev is very expensive, esp in the UK - it costs £400 just to do a character storyboard, I have a dev license from Microsoft, but need more funding for the project.

If you have a suggestion on the tiers, I'd be happy to hear!
