So from the wiki page:
Release Model Offered for download on the internet. Game will be released in several 20-30 minute sections of gameplay called "modules".
I assume this model was designed to allow iterative game development (so each release holds a new chapter) but this holds problems as small things can change making the previous models incompatible with the new one.
Personally I think we should try update by update release model (like used by Mount&Blade) since that would be easier to maintain. But since this still allows changes to the story we should think of patching save files to make up for any changes (a save game editor, maybe).
There is almost no differnce with the "modules release model" and the "update by update release model" accept that the later one is a complete new download which is easier to maintain than going through all the previous modules. I did read in viewtopic.php?f=18&t=745 that this is easier, but I think it's harder to delevop.
So is the above release model still valid? Because I haven't seen much topics about it (couldn't search on "module" alone)
