Expansion model
Expansion model is based on a combination of:
- paying major DLCs that unlock new gameplay (new playable characters or new features)
- free major content patches that contain the updates on core mechanics and essential features used by the DLC
- paying minor DLCs that unlock music, graphical or customization features that do not impact gameplay
According to CKII project lead, some features were cut from base game to fit in the 18-month project duration and a few ended up in either DLC or free content patch, who is basically paid by those who do buy the DLCs.[3]
One of the lessons learnt from Sons of Abraham expansion and the dilemma between putting larger more central features in the DLC, but keeping core mechanics in the free patch is that "future expansions will either have to unlock new areas of the game or feature more noticeable (graphically or through sheer weight of content) stuff."[4]
Starting with Horse Lords, all graphical and music packs are marketed into a single "content pack" named after the associated major expansion.[5]
Going further into the reduction of new DLCs, starting with Monks and Mystics packs are directly bundled inside the expansion.
Quality assurance
Being a sandbox game, CKII testing process is not trivial. Paradox has reported running nightly automated playthroughs in Observer mode, to check game balance.
After the difficult launch of patch 2.0, Paradox acknowledged an overload and complexity issue regarding QA, and decided to rely more on Steam Open Beta patches while at the same time hiring more QA and increasing size of closed beta test group.[6]
配置
- 主条目：Optimization
RAM and CPU load has been the limiting factor in expanding the map,[7] due to the low system requirements dating from 2012 (32-bit, 2Gb of RAM, Intel® Pentium® IV). As the in game years go by, the game may slow down due to:
- the increased number of characters, and the time required to process events and decisions on them.
- the increased character and title history, increasing auto-save time.
Despite many optimizations, the release of Rajas of India patch, with the inclusion of 327 new provinces (+22%), had the most noticeable impacts.
In order to be able to continue adding new content, a special focus on optimization took place during the development of patch 2.7, with a -30% to -50% speed improvement.[8]
