CSR – what companies do to be respected and appreciated in society. Would game developers see the value in becoming a benefactor in education? This is not in itself a possible revenue stream, but might indirectly lead to that. Increased regular sales – in continuation of the above, having access to these games in education, and seeing the effort of the developer might create sympathy and interest with students and teachers, who would, in turn, buy more of these games outside school. Subscription – it could be possible to build a service, that schools etc. would subscribe to. Extra value packs – like DLC & IAP, it might be an idea to sell material, that makes the exploration and use of the game richer in some way. As an example, many teachers would need a guide of some sorts. Donations – as has been shown by the Humble Bundle (by the way, go buy the current Indie Bundle) and others, many people are happy to donate (/pay more than required). It is plausible, of course, that these dynamics are completely different in education. External sponsors – there is an increasing interest in the possibility of private companies sponsoring education, and that might be leveraged here. - www.mathiaspoulsen.com
