That should equally a few more inputs.
Maybe enough for neo Geo?
Now I gotta research this.

Marketing can be deceiving because not all 40 GPIO pins are I/O pins. I forgot the actual number.

It should be half.
if they followed the same scheme as the original.
so 20.
which should be enough for two joysticks with 6 buttons each.
admin/coin/start buttons would have to be handled by USB which isn't too bad an option.
I'm just not sure exactly which fighter games would work on a RPI or an RPI2.
i've read recently that some people have Final Burn Alpha Libretro Playing street fighter 3 smoothly on the RPI2 but I haven't tested this myself.

There are 15 pins available, plus 4 extra if you are happy to solder a header on = 19.
So for my setup:
4 directions, and 2 buttons = 6
x 2 players = 12
Plus p1 and p2 start and coin leaves room for 4 admin type buttons

ok.
So the classics.

I did exactly this....
So I ended up making my own connections, but with the pins on the Pi end pre bought.
I had a 20cm cable length with one of those little pin connectors on each side.
I chopped the end off, and reused it. The other end, I crimped myself with spade connectors of various sizes and then simply spliced/soldered them together and put a bit of insulating tape around it
Note, soldering is important, because they would just not hold themselves with tape alone
worked well for me :)
If I were to do it again, id definitely go for either crimping both ends myself, or a breakout board like you suggest. It would just be cleaner, and easier to trace the cabling once its all in there
I have joystick, 6 player buttons and 3 more for start/credit/select/exit, so the wiring got a bit tiresome at times!
