LOL! I painstakingly read the GG long before I touched any Steel Panthers scenario (WinSPWW2 at that time); to the point that I set the page as default every time my browser opened. Oh... how much I loved to finally have WinSPWW2 at that time; was very much thrilled with the complexities and realism it offers, and a myriad of pre-made scenarios! (just moved from shallow military games like Close Combat, Soldiers, FireFight, etc). I found the GG to be very much a helping hand in understanding the concept and mechanics (my favorite chapter was Game Play Notes back then). Many people think that SP doesn't have a steep learning curve to master, thus they don't really see the need to actually read the GG.
Anyway, thank you Mobhack for planning to review that rally code!
