I'm just on the tail end of a Navarra->Spain game picking up all the Spanish achievements + forming Rome and HRE. The need to run through the Spanish mission tree and converting enough culture to Basque before forming Spain delayed me too much too get into East Asia in time. Thus, it seems not unreasonable to finally go for WC next run, but I don't know who would be easiest to start with.
Btw, personal restrictions for achievement runs:
Only OPM starts unless the achievement specifically requires a certain nation.
No no-cb delaration.
No culture flipping to exploit mechanics. (like country formations or reducing coring cost)
No religion flipping outside starting group.
No weird capital moves.
Any ideas, I'm very open to suggestions though I've been looking at a few countries myself already.
