EAW, and by a wide margin!
None of the other three games have anything like playing SFB on the dynaverse. I bought EAW hours before it hit the shelves (I made the stock boy go in the back ang get it) and I still play it almost daily when I'm not busy designing new D2 campaigns.
The other two were good;
*SFC1 was fantastic, and very worth the money I spent on it. But it had nothing like the DV. There is nothing wrong with SFC1, it's just been supplanted.
*OP kept all the old D2 bugs from EAW (including the three-year-old unfixed patrol bug), and then introduced more. It can be pared down to it's good essence (and I'm sure it will be if anyone ever fixes it's D2) but I'll still never completely forgive it for taking that first big step onto the slipperly slope of SFC3.
SFC3..... just not my bag. 'Nuf said. I do wish it had a different name.
But of course, the
BEST version will be GAW (you know...... some day) -- It should have all the fun of EAW but with a greatly ehanced Dyna experience and more admin controls over how the universe operates. Keep hope alive!
