So the last Boston Post Mortem meet up event took place at the UK Trade and Investment office as part of the consulate.
Akihabara is a 2D (bitmap graphics) game engine based on the canvas tag, part of HTML5, a great platform for quick product prototyping, with very little knowledge of coding or web work to get simple stuff together and working.
Some information about the engine with tutorials can be found here.
Fantastic documentation about the engine can be found here.
The Boston Game James website has a copy of the presentation which includes a great list of links to the various demos and other engines, which you can find here.
