Marverni will be the winner. In almost all categories (provinces, income, gem income, Dominion) he has as much as the rest of us combined. And most especially Research...how many Level 9 Schools does he have at this time?
The next closest rival, T'ien Ch'i, is fighting two foes and just lost a major battle (and his prophet). Pangea's army, the largest, is composed primarily of maenads and will not last against Marverni; he can barely make headway against TC.
I'm happy to continue playing (given my recent victory against TC

) but the winner is very obvious at this time.
