It is a moot point, and I stand by it.
By your situational irony scenario’s, lets say Japan declares war on Russia the turn Germany takes Moscow. After Germany takes Moscow lets say USA takes Germany/Berlin on the same turn!! Uh oh! The allies just wasted a good chance to collect the IPC’s Russia had, BUT, by YOUR method, the bonus totally goes down the crapper and is a MOOT POINT. Because if you’re talking about taking capitals with ease to a point of if Moscow falls so easily than Berlin can just as easily get taking by USA/UK to get that bonus back.
Pelanderfunk, it doesn’t matter in your game. It could actually work against Germany. He see’s that 12 IPC go to you, and Germany could make a risk that he shouldn’t. Either way there is no reason not to give the bonus right away. Played enough games of global to forget many things, and waiting to give Russia money would be one of them for sure!
