I've been thinking about getting a couple of the Mongoose setting books: the Hammer's Slammers one and the Babylon 5 one.
Finarvyn,
I can only answer for
Hammer's Slammers because 1) I've been following the series since the first short stories came out and B) I have that setting book.
1. How well written are they?
The setting book is written is well as any of the other Mongoose products I own. While it's neither noticeably worse or better than those other products, I'd rate it as good.
Do they capture the essence of the settings they are trying to emulate?
Up to a point. Two examples: Drake's
Slammers universe has FTL comms, as seen in
Cross the Stars, and interstellar travel which is trivial in both cost and time, as inferred by many stories. Sadly, because the
Traveller rules are being kit-bashed to fit Drake's setting, interstellar comms and travel costs/times become more
Traveller-like and less
Slammers-like.
Of course, any effect those examples may have will depend completely on the type of
Slammers campaign you run.
Do they still have that Traveller "feel"?
Yes, and that's not a good thing.
I got a definite impression of
Traveller being "forced" into the
Slammers universe rather than being "modified" for the
Slammers universe. For example, there's a few sentences containing a rather lame excuse in the section explaining UWPs about how most of the
Slammer colonies developed governments which featured actual nobility. Very few
Slammer stories are set on worlds with nobles because Drake is a good enough author to realize that actual nobility is a low probability. Instead, Drake shows local political
elites which are something entirely different and entirely more probable.
(1)
Rather than modifying the
Traveller government tables and descriptions to better fit the
Slammers universe, Mongoose chose the easier route of modifying the
Slammers universe to fit the
Traveller government tables and descriptions.
2. Are the rules streamlined or changed a lot, or if a person is familiar with regular Traveller (either CT or MGT) will things make sense quickly?
Most certainly yes.
Buy
Slammers. There's enough in there to make the purchase worthwhile and you can easily change whatever you don't like. After all, who runs a setting right of the box?
Regards,
Bill
1 - So, what's the difference between nobility and elites? Well, what's the difference between the House of Windsor and the Kennedys? Get the idea now?
