Hmm, traffic is down.
Anyway, my big beef with T20 is that it is a D20 system; i.e. experience points / rewards system. To me experience in Traveller is bundled with your skill. If you were in the marines with a combat rifleman of 5, then your experience and education elevated you to that state.
With D&D the whole "life is a journey" mentality I think works for the active adventurer who is constantly using his skill, but that said skill will cap out, and that experience only buys you so many active combat moves and counter moves for your character. And I think that's where it falls apart with Traveller.
I think if you were to start adventuring at 18, then the experience system would make more sense, but most Travellers are well over 30, maybe even have a pension, and have skills that have capped out.
Wiegell's opinion that T20 has a lot going for it I think is true, but I really wish he had reviewed the earlier iterations of the game, and then compared it to Star Frontiers or Gamma World, as well as commented on what Traveller is supposed to be; the all purpose generic set for your sci-fi gaming setting.
