I just had an idea to possibly improve galaxy cooperation (between planets)
Allow the MOD (Minister of Defence) to build and deploy a Mine Field around the galaxy.
This would require that the MOD planet be given access to some extra page to build and deploy the mine field.
Cost of building it would come from a fund set up specifically for it, that is funded by a 2% - 5%per tick tax (variable set by GC) Funds cannot be used for anything else. By default the Tax option would be switched off and require a vote by at least 2 Galaxy officers to switch on.
Now to the mechanics of the mine field.
1) Mines can be constructed and provide Equal Defence to all planets
2) The Mines can only be made active for short periods (say 5 ticks)
3) Once activated they are spent and die at the end of the period of use.
4) Mines would be capable of only affecting Structure Killers (obviously this would mean that SK's generally would have to be SK's and not any other ship type)
5) The mine field cannot be detected by any sort of General Scan type, other than as below.
Now to give a counter to this, and to possibly introduce further cooperation, a Mine Scan should be avaiable to the MOC in each galaxy, again would require construction of scans/amps in a soecific area, but as they cant be blocked would only require a throw away amp/scan. Minimal cost 1k C/E per scan/amp that again comes fom the fund above.
Feel free to blow me aways
