I wasn't exactly sure where to put this, so I thought general was good.

The Problem:

Winning purely by culture is fairly easy to do with the new expansion's added culture research and starbase culture, but the problem with it is it's very, very boring. I've won a game by culture once, and only once due to the lackluster feel of winning that way. It took 4 planets to take out an entire system by culture with the Deliverance Engines and Temples of Communion that the Advent have.

What to do about it:

Make it FUN to win by culture. The only viability at this point to win in this way is playing Online with a friend, while he sieges the planets, you culture take the rest. Still, it's not much fun sitting back on your planet in a safety net. I propose with the next expansion(s), adding more culture research that adds the "Your planet didn't go peacefully, and instead a lot of people were killed in the process" feel of Sins. Who honestly enjoys seeing the notice pop up "Another planet has broken under your influence"? It's not fun.

Ideas (to be updated with feedback):

If a planet is influenced by your culture, but has culture-blocking things like ToCs/Capital Ships/Starbases with add-ons, have a late-game research/artifact that causes those entities to slowly lose health under your culture, and have them go "offline" and eventually explode. -Me

Add an achievement for winning by not building any ships, and winning by culture.

I started it off with two. Comments/questions/concerns? Who agrees here?

TL;DR Culture is really boring and has almost no stimulating gameplay when winning with it.

Thanks for your time.
