You should be able to complete the campaign goals around 250 BC if all goes well.
Lol. If You blitz then Yes. But I dont recommend this type of playing, its just not fun. You loose a lot.
When I played Getai last time (0.74 VH/H ) I ended it about 220BC because of CTD and by that time I had Hellicarnassos and Ipsos only. Romans just kicked me out of my homeland
The whole game was a blast.
