I am not saying Swordfish should go open-source (they obviously haven't seeing that Codies have put their own money into it) but that an open-source game would work from scratch. Open-source programs are always much more efficient than commercial programs, because there is no profit margin. And with the modding community, that is not really going open-source for Codies. They are just setting up a platform for gamers to share mods, be it squad updates or gameplay patches. This would mean (a) the viewers are happy with the game, (b) codies don't have to produce the patches themselves and (c) long-term gaming!
