I like reusing the old look and names. The old players will know instantly what they need.
I dislike that. I won't get Mongoose Traveller stuff if its a rehash of CT. From the little I've seen, that's all it appears to be. I'll only get new stuff that adds to the OTU. I won't use the main book for combat or PC generation thats for sure.
I like the B5 RPG material based off of D20. Too bad Mongoose missed the boat on the D20 license for Traveller years ago.
