I like it, as long as it will bring some life to the game again. Two possible names:
Progressive Coalition/La Coalition Progressive
Citizen's Federation/La Fédération Du Citoyen
La Coalition Progressiste and La Fédération Citoyenne.
Something along the lines of the French "alliances"
Plural Left (PS, PCF, DVG, MRC, RDG) vs. Union of the Right/Centre (UMP, NC) and allowing some parties to be outside of that (such as the far-right or extreme centrists and far-left).
Forcing parties into one of the two alliances wouldn't be good IMO, we should have larger alliances (like the 2 I described above) and some parties outside of that. I was thinking, for now, please correct me if I'm wrong:
Plural Left (Social Democrats, Labour) vs. Union of the Right (Conservatives, PC) vs. Centrists (FDP, SoCred, Social Liberals)? Or join the centre and the right? Centre and left? Make one of those not aligned with either?
