Opa himself has been long gone, it seems?
iirc Opa left for a few years and then came back. He's had some pretty decent tech jobs, which is hilarious considering what comes up when you search for Teh Kao Yang.
Someone please give me a timeline/summary of Gaming-Age, Oppai-Age or whatever you call them. I'm a filthy noob, but I wanna know what it was like in the old times. Tell me, grandpa. 
- GAF has been around in various iterations since the late 90s, including a time when malware would get installed thanks to ad banners (the more things change...)
- Opa Opa had a meltdown on GAF when Sega discontinued the Dreamcast. He was banned. So this was 2001.
- Opa Opa created Opa Ages. This place was pretty anti-GAF but Amir0x and EviLore were members and regular posters.
- EviLore bought the forums off of Gaming Age in 2004 and turned into NeoGAF. Many former GA staffers (Mandark, Drinky Crow, etc.) remained as mods or admins. I think Drinky Crow wrote his infamous "vociferous laudations" review on GAF or Gamespot (I could be wrong).
- This was around the time (2005-2006) where Amir0x jizzed on a printout of Olimario's fiancee's nudes, took a picture of it, and then posted it on OA. Amir0x is a classy guy. Olimario traded the nudes originally for a PSP to m0rphix. Somehow the nudes leaked even though m0rphix insisted up and down that he didn't do it. Speculation was that Olimario traded the nudes for other favors on OA and the leak happened there. He wound up marrying her and I think they are still married to this day.
- OA is full of losers so it was inevitable that drama broke out. There are probably at least a dozen different iterations of OA from then to now. Most of them only lasted a few months.
- Somewhere around 2008, Saint Cornelius tried to mack on whiteACID and it blew up in his face. One of my most favorite moments on the internet.
- OA IMO started dropping off in terms of interesting shit a little after the Saint Cornelius debacle. OA still exists to this day but it is a lot slower now than it used to be 10-15 years ago.
- A bunch of dipshits who were responsible for turning GAF into shit made a GAF spinoff, Wasting Your Life. WYL fell apart in six weeks. This was 2009 or 2010.
- Funnily enough, a WYL spinoff was created called Cyniculture that failed to launch. costanza pretty much disappeared. His butt buddy, snesfreak, disappeared as well but will show up if you post about him enough. I bet that loser still has a Google Alert set up to alert him when someone talks about him.
There's a bunch of stuff left out here that can get filled in but those are the highlights.
