Favorite Country to start a campaign in EUV?

For me, of course it's Verona, but I had a lot of fun as Athens and Aragon.. Otherwise if I just want to chill, I usually start in HRE!

Nothing like shitty old Meisen for me. Or Genoa and Morrrrroco

Personally, no favourites here, granted I'm not able to maintain long-term interest in EU5 much these days. ADHD does that and honeymoon period is kind of over. I do have a strong affinity to Brandenburg, but calling that favourite is a stretch, not actually being a masochist myself. As I can't stave off ADHD-style boredom or frustration infinitely, I basically had to resort to the odd mod, and more notably, my own numerical tweaking mod, to try to make the game enjoyable enough to push at least halfway through a campaign. My personal style being looking for crazy/silly country formation chains, I'm currently just nursing an England -> walloon France -> Germany with probably Europe as a cherry on top kind of run in the back of my mind.
