Is using a VPN to play multiplayer games with friends safe, or dangerous?

[anningrad]

I remember using something called Hamachi a few years back to play games online with my friends when we had connection issues, and nothing ever happened from this, but I recently read something in the Steam TOS that seems to imply that any VPN use whatsoever could lead to my account getting banned, and I only just learned that hamachi is a VPN.

How dangerous is using a VPN for playing games? Are there are similar programs that pose no risk? I just wanna be able to play EYE Divine Cybermancy with some friends but the game is just annoying to get everyone connected without something like Hamachi.

If it is safe, what's the best program to use?

Also, is port-forwarding safe?

Thank you.

Fair enough. Not sure where the best place to post this is, so decided to ask where I figured it would be acceptable.
