Tidy up stats tables. Amalgamate guns/dmg, with EMP guns or damage aiming at E/R. Have E/R work like EMP armour rather than the crazy headache sytem we have now. Far more intuitive and shouldn't need much work.
Thread.
Improve ingame attacks. Ruler or planetname is pretty much worthless info. Race, value, size are useful. Also, optional numbers of waves, ability to open/join waves perhaps.
Another thread here.
And another one.
Cut down protection to 24 ticks or remove it altogether.
One thread here. Can be simplified by using current 'upgrade planet' style of applying research points, roids etc. Allow people to pick prebuilt planets or to assign points how they please.
Restructure scans so that new players can attack. Start with a workable planet/unit/landing scan that go through distorters. Maybe make last scan research 'improved amplifiers' or something, which would reduce all scan costs to 1k of each. New players can still play and scanners aren't vital. But there is a tactical benefit to having them.
All are KISS compatible and shouldn't be too demanding on coding time.
