Insight
Adventurer
Hey Insight, the Deep Red thing is definitely coming along nicely.
Now I feel the need to rock the boat a bit. If Insight's game is going to be GURP's 4e can we do the Traveller game in 4e too? I fear jumping back and forth between editions of an unfamiliar system is going to be hard on my poor old brain.
I'm going to be out of touch until Friday.
Thanks for the compliment!
In terms of 3rd ed / 4th ed, mechanically, you won't notice much of a difference. Skill checks (the heart of GURPS) are exactly the same, although some skill names are different. Some point costs (ability scores?) are different as well, but skill costs are virtually the same. I'd have to look to see what's different between the two to be exact, but generally, I don't think it would be all that hard either way.
Obviously, it's ultimately up to Leif how he wants to run his game. For mine, I'm planning to use 4th ed mechanics, but I'll still be referring to some 3rd ed sourcebooks that have not be released for 4th ed (Mars, for example).
