Also, I respectfully disagree with The Pizza Guy's conclusion on this, in that if the GP's to be used in this situation would have less effect and less casualties than the regular GP's, than the defender's economy wouldn't be totally drained, and his defences wouldn't be completely destroyed.
However, I think that this option should be allowed in multiplayer and single-player, because:
When dealing with bribes, the ability to negotiate and/or compromise, is especially essential.
To negotiate/compromise, could have far-reaching repercussions, like the formation of trade alliances, new allies, the trade of resources, help in combat, and all the other good effects of negotiation.
Benefits: multiplayer - human interaction allows for a lot more flexibility, choice, and bargaining power, single-player - see above point.
It also adds a lot of depth to AOM, making it a more well-rounded game.
Or you could also have preset options available (like a choice of what GP would be used if whatever payout (from the choices given) would not be paid) to use in single-player situations.
Also, who said that it HAS to be high payout to low-effect GP? It could be that the attacker or the defender could threathen each other with a GP or high payout to avoid it, and then have several options for a response:
Yes,
No,
Negotiate (only in multiplayer), or
Custom Yes/No Reply (type in your own message, but have ability to negotiate with opponent if conditions/reply are good) (in single-player and/or multiplayer).
To make the threat of the use of a GP against you if you don't payout the price negotiable, has a lot of effects (see above reasons to make this feature multiplayer only).
This way, it becomes a win-win situation!
And while I'm on the subject, the ability to negotiate/compromise can be applied to other areas of the game. But now I have temporarily run out of ideas (nobody's perfect), so does anybody else have any ideas/comments/suggestions?
