Na, I didn't know a Jay. I can't help on the moongames lineup either, haven't got a clue tbh, but 'con' certainly rings a bell and you're right about sae being called 'Ultra' - I vaguely remember that now.
My brother was turgidmonkey - I'd be very surprised if you knew him, he kept an even lower profile than I did and he stopped playing quite early. I used to be just bern / berned in the old days, then eventually became berners in later years.
We played with so many different players through the jogon years. I think we originally formed around 2005/06 and played on well into CSGO. Some random names you might know: RoyBacon(old days alias was Stealth), c0dec, ironmonkey, Elite33, Eagle, MCG(goddeh), madSpunk, Song, wute, redH, steveoh, punt, sorted.
Good times indeed man! I really miss those early innocent years when I was a little kid first discovering the game - I used to have to share a PC with my brother (which basically meant I mostly sat and watched him play), so to get in as many hours as possible I would wake up stupidly early before school just so I could run around on a public server for an hour or so.
I don't play much these days, but I was still playing CS on and off up until a few years ago. You'd be surprised how many oldschool players are still playing here and there - I bet your old virtuoso boys are still knocking about somewhere.
