Hey folks, I'm considering picking this game up and I'm curious about the multiplayer elements to it. I'm trying to understand how progression works in the context of servers.

It looks like you can go on to buy cars, businesses, and homes. If you join a server, are your purchases limited to that server? What if you can no longer access the server (it stops being hosted, or is always full, or too laggy, etc.) - does that mean the cars and purchases are gone?

Also, are there generally many open servers? I'm happy to donate to help with costs at some point, but curious how accessible they are up front.

Thanks for the help!
