I have a population of ninety at the moment. Is there a way I can build more houses so I can have more people? Or is that it?

Welcome to the forums Daniel. I regret to inform you that you can't build more houses. If you're playing VV1, 90 is the max population
(though it CAN go slightly higher in certain circumstances).
If you're playing VV2, you can get a higher population, but just how is a spoiler, so I won't tell you unless you specifically ask.

p.s. be sure to post your intro so we can all greet you properly!
We love to make new friends, and posting an intro is the best way for everyone to know you're here!

whoops, i didn't do that yet some people know me!\

I have seen screenshots and the population is 400 and something

Those were early screen shots of a development prototype and did not show what the final game would be like.

ya I think 90 is the limit in vv1.

Bwhahahaha! 91! Awesome! ...Someone had twins. Apparently the games pop limit is kind in the case of twins.
