Personally, my opinion is the game gets a LOT less fun the more books there are for it. The game and the players get more and more "fiddly" and it starts to become more and more about the gear and whacky new rules than it does about the, well, game. The roleplay and the characters.
I'm very much looking forward to Missions being "stripped bare" for a while, honestly.
There are other games out there for those who think that the toys supposedly--though it is highly doubtful--"get in the way". The Unisystem games come to mind.
For the record, the following reply is extremely sarcastic, and a little rude, but I feel ranty and need to say it. I have put it behind a Spoiler tag, and if the mods want to take it down or tell me to take it down, I won't object.[spoiler]Or...and I know this is a weird concept...they could play Shadowrun the way they want to play it.
Now hear me out here before angry rabble show up at my door with pitchforks: I know that the
right way to play the game is to use every rule in every published book exactly as written, but
no OPTIONAL rules of course, and optimize every possible aspect of every character so that they are built
correctly. I'm not arguing that your way of playing isn't the
one and only true gospel of HOW TO PLAY SHADOWRUN
tm.
Some people, however, do prefer to play without a whole bunch of
incredibly important additional books, but these
deviant scum still want to play Shadowrun without access to the full catalog of holy "toys". It is understandable that you might suggest another game system, like the
heretical Unisystem, but I doubt that is going to satisfy these blasphemers. They are going to continue playing Shadowrun wrong, and while
I certainly know that the fact that there are individuals playing the game differently from you
(and daring to even ENJOY doing it that way!) is ruining the sanctity of your game and
slowly destroying the whole system of Role Playing, there is nothing we can do to stop them. [/spoiler]
