I feel like the developer should actually get some legal advice. In the U.K., “the crown” does not refer to the monarchy, but some legal entity that might as well be the state.

The centrism is a side effect of First Past the Post surprisingly. Look at countries with proportional representation. Compare the far right seats in European countries to seats here held by the Brexit / Reform party. If I recall correctly, the 2015 election results are one of the worst, with the Brexit party getting close to 13% of the vote and only 1 seat.
FPtP tends to force parties to compromise before election to gather support. Successful PR governments require the compromising after the results to form a consensus.
The results from this paperare quite interesting at comparing voters to how MPs vote. Essentially the average CON voter is actually more socially conservative than how CON MPs vote. Similarly the average LAB voter is also more socially conservative than how LAB MPs vote. Essentially if you make the populace pick, they’ll prioritise social conservative policies first even if they wanted more financially left policies.
