For Games With A Set Number Of Rounds, Is There Such Thing As A "Rush" Strategy?

I've been thinking about the strategy circle (i.e. Rush is weak against tanking, tanking is weak against long-term econ focus, and econ is weak against rushing).

But in my game, there is no way to rush the end game. The game will continue no matter what, and players who are at a disadvantage early can still refocus and be generally fine.

Are there games with unconventional approaches to a "rush" strategy? Like claiming lots of small batches of VP early, or accumulating lots of resources early and hope your early advantage carries you through the end game?
