Please consider my thoughts on allowing the Royalists a reasonable chance to take Oxford early on.
There is a Royalist Commission that can be played for Oxford on Turn 1 but it seems to have 0% chance of happening (I replayed it 15 times). A simple tweak could make this high probability or a certainty. Royalist loyalty is 24%, Parliamentarian 26%, Neutral 51%. One wonders how accurate this is. While many of the citizens more favoured the roundheads the university stayed staunchly Royalist even supplying war funds during the war (and was punished by Cromwell afterwards). in any case another thing the Devs could do is allow a Royalist Gain Support card to be played in Oxford on Turn 1. I'm no expert on this area of history, but Oxford is a complicated situation early on that could be modeled better.
