There's other win options, at least in Dom 2 there was.

If I remember correctly these options were:
- Total conquest OR victory by eradicating all enemy Dominion
- Research victory
- Victory through control of victory points
- Victory through dominion
- Victory through getting a certain number of provinces

And the victory conditions don't exclude each other, you could eradicate everybody in a research victory game and win.

You can't enter diplomatic relations. If this a game breaker for you, then it is.
