Yea, that was sad. As soon as you save for King Tiger....bugsplat.
I think you could have won early after that 300 munns explosion. Maybe gone stukah after that and not worried about VPS...it's a strange bet on what you could have done. Maybe bugsplat would have happened regardless.
Never quit just because some guy calls GG in like the first minute of a game especially when he later throws away his flak to the US flak just as careless.
Other than that...it was a pretty fun game. I have been playing soviets lately so I wasn't even doing that well, but apparently well enough to get a 28 min VP win in.
