Fresh implant looking for ways to meet people

Hello, I just moved here from Utah. I've been to GB before, I was raised in the Racine County area and then left the state for about 14+ years and am now back in Green Bay.

I was wondering if anyone knows a good hangout spot for someone a little in the nerdier type? Maybe an arcade bar, local Dungeons and Dragons guilds, things of that nature. I don't really know anyone here and would like to make friends.

I'm just a 37 year old male looking for ways to socialize.
