In the end I was offered enough money for the work I had done on caching and some other bits that it was silly not to take it. :) I'd love to have another go some day. There was Qoppa which was intended to be an extensible Browser game server written in Python. That fell apa…

The idea was to make a reusable FOSS engine then build some commercial games on it :) the market is quite competitive, good graphics is becoming quite important.
