This product is basically a copy of two pages of Mongoose’s Traveller game. Nothing new to see, pretty much useless on it’s own, and flatly it seems that somebody is attempting to make a bit of easy profit out of an open system SRD.

This is really useful and can be used with the Traveller SRD.

This has rules for generating characteristic scores and modifiers without having to buy the Traveller core rule book. It also has tables for the Education and Social Standing characteristics, which are both very useful. The pdf version of the product has an Old School/reto-clone feel to it and it's great that they have provided the product in different file formats because not everyone uses Microsoft Word. You can use this with the Traveller system reference document as it slots in seamlessly and you can modify it if you want because everything in it is Open Game Content.

This product is very short. It seems to be intended as a part of a complete SRD, but since most games have their SRDs available for free and in one piece, I can't understand the logic behind this one. Additionally, this seems to be simply the same rules as Mongoose Traveller with just a couple of differences. And the entire Mongoose Traveller SRD is available free and in one place.
