I've been thinking about what I thought since last night. Initial reactions were very much cranky, but after thinking about the changes, my main concerns finally simmered down to just a few and I think that as long as Crafty keeps them in mind, it'll all be cool.
I had to first think about what the differences between SC2 and FC were and where my complaints with FC spawned from. Most of them came from the "there just isn't enough X" in terms of Fantasy Craft. X typically was for me: Support in PDF expansion or book form, Gear, and classes and feats. I think that in time (and with the addition of these new core books) most of these problems will disappear as concerns for MC in general.
For Spycraft, I kinda just got the hang of it better, but thats more because I've played it with the people that made it and a bunch of the Lspy crowd and knew it better. Plus its a mature game with a ton of cool support. The announcement of SC3 basically had me fretting mostly over the loss of the gear and cool stuff in the name of simplicity. With all the amazing things they have in SC2's gear section (and all the PDF suppliments) I hope they are able to just mush it all together and make it into one big happy game and not lose any of it, but sadly I know thats not how the industry works.
So, I figured I'd just toss out a few suggestions on what would make me happy:
-With a new chance to rework the gear section, could we:
a) get all the cool things from the bag full of guns added into the lists without needing extra pdf purchases again. That'd be great.
b) if we end up simplifying the rules for guns into "all pistols do X" and then using manufacturers or add-ons, could we at least get a list of examples of common ones (i.e. The FN FiveseveN is a pistol with this material, these bullets and this craftsmanship) A list of firearms with names really helped some people in my game identify what it was that they wanted (and at least helped them identify what it was they really liked easier). If guns become generic I will be somewhat sad, but will understand.
c)Don't come at this from the less is more approach if at all possible. Its worth the extra pages to add in extra random gear in that would otherwise get glossed over IMO. Players spent a lot of time between games just "shopping" for what it was they wanted and I think that really enhanced the feel of our modern games. The rules for common items were awesome, and I fully endorse a big section on them. Just feel free to not stat them. Its cooler to make the GM decide on rules for them and such (like random +1 gear bonuses on skill checks and such). A funny suggestion along these lines I had was instead of coming up with 'costs' for them all to save you time is add in a 'rule' where if a player can find an advertisement on the item's cost that's how much it would be in dollars. (i.e. Player asks "how much is this crowbar?" GM can either tell them a generic price or have them look it up online or something and find a real life cost. It could be funny. Maybe worth a little blurb sidebar as a suggestion on rulings)
edit: One addendum to this thought in general along the lines of thought "We dont want people spending all day looking in the book instead of playing the game" I think that having the players browsing the book for gear and ideas and such was what really got people to get involved with the game. It draws them in and helps them get a better understanding of the game as a whole. If people find their players are spending too much time shopping instead of playing. There are ways (and opportunities to suggest more in the book) to keep them focused elsewhere and do their shopping/studying in RL downtime instead.
-Don't lose the classes that were too "focused" like Hacker and Wheelman. Instead, perhaps broaden their class features up a bit but keep the concept the same. I'll have to create some sort of "gamers for the ethical treatment of wheelmen" group or something to protest otherwise.
Ultimately, I think my concern is losing the feel of depth that SC2 had for the genre in the name of simplicity. A close second is my fear of having to re-buy all the cool new PDF additions you guys have made recently again. I'd love to see all of that re-purposed right into SC and 10kB at launch, but I know thats not how the system works. Seriously though, Heroes and Transmechs are awesome, I was looking forward to using them in an upcoming game but with as long as our game que is its more likely SC3 will be out by the time I want to use them... (with any luck...)
