The Unreal 2 stuff convinced me more than anything. With Unreal's long development, I figured pretty much anything was possible. I wouldn't have believed it if I had known who the "source" was. I just don't get what he got out of it.
I'm not sure if I should say it, but afaik he did have some mental problems, he could have believed it himself entirely(and after what I heard about him it's not surprising). He even went ballistic during 2011 when I stated it here in the forums that it was hoax and added this to the readme of one of his maps:
"Once I return to the main Unreal/UT scene... MR. Leoo(T.C.K.) is going to have to explain to me why he went behind my back and told LIES about those fucking Unreal Alphas and Betas to random forums, when infact they are true! Just because there is no proof, that does not mean that it's false 100% of the time! I'll never forgive you as long as I live, so FUCK YOU! I used to look up to you and shit, thinking you were a great guy, and I prayed for you to heal of your condition. Well, I feel sick to my stomach everytime I think of praying for you...you useless pile of shit, GO TO FUCKING HELL!!"
And yet another line: "Now, with that all said and off my chest...meet me y'all (except you Leo(T.C.K.), you motherfucking double-crossing bastard ^^ :/ ) on my clan server, where almost every Saturday we have our "Clan Event"."
I think that can speak for itself. The fact is even back in the day when this was announced, he avoided talking to me about any details, one can wonder why, instead he told lots of fake details to others, probably not to me because he would figure out that I would call it a bluff. About nothing of the stuff he said turned out to be true, and perhaps this was one of my motivations to search for beta content myself(one of the reasons to see if anything he said was true or at least approaching it). Hell I even felt bad that I might have been the cause for slowing down the process back in the day or somehow screwing it up, but it was all out of convenience stuff and all fake.
EDIT:
But perhaps not dwell on the past too much. I hate how I used to act sometimes on forums too, not that there weren't reasons behind it or my condition, but I should have been more subtle perhaps (in the end it only turned more people against me, people I had nothing against, even though that could have been avoided). I did have a lot of anger problems myself in the end and sometimes such outbursts made me look foolish/not credible, but I don't care about that now anyway, it's all behind me.
