No, they weren't, but you were the one who said Gaider was famous for being a modder and not a designer - and I said "uh, no."Hmm, Ken or Minto were Bioware employees?
Yes, I said it - but it is not complete what has been said. Gaider has not been "normal" modder, he has been from Bioware. You can call it as you want, "Bioware modder" maybe... But this is the role that primary made him "famous". And note that in "Bioware modder" is not "genial designer" or something... That's why people know him...
Avellone is maybe better designer, however he is not "known" for community like Gaider. For people in IE modding Avellone is - compared with Gaider - rather anonymous head somewhere in corporation. Maybe people out of IE modding know Avellone more rather than Gaider (simply because they don't know about Gaider at all) and (...and thus) give Avellone more glory - because such people don't know IE modding, Gaider, Ascension, etc. at all. But we are in IE modding here, in IE modding where Gaider has been active, Gaider is familiar for us - all we know that he has worked on BG2.
One notice, maybe it has some importance, maybe not - from all IE games is BG2 the most popular, for modders probably too. And Gaider has his credit on BG2. Not Avellone. Avellone has his Torment (and IWD, and Fallout, etc. let's stay on Torment, his most noticeable work)... well, Torment that is for me much, much better than all Baldur's Gates, but many people don't like Torment or don't play it. So someone who likes BG2 more than Torment could simply prefer Gaider more... This could be one of additional (but probably minor) reasons why Gaider and not the others. We cannot see it as black and white world "Gaider's glory = he is designer-god: yes/no?"
