I test v6 b7, playing as France, on Prince level, tiny pangaea map. Quick speed.

Now, after killing Spain, every other civ starts to hate me (denounces me, I am warmonger - well, yeah...)
/This is fine, and with WWGD v3/
EDIT 2 (22nd of January)
btw turns 100 and 125 I quickly killed off the Russians (1 remaining city they had)
and then started a war vs Japan, which went rather sluggishly, as its capital was very hard to take (hils, hills, everwhere, plus a river).
So, instead Tokyo, I went for the two other bigger one and puppeted them.
My army is of the same size since the Spanish war: ca. 20 units (with a few workers)
On turn 125 I am slowed down by severe unhappiness (-19) and lack of money.
