How about a mod with these specs:
* Nerf high-end influence starbase mods slightly (+80 maybe, not +100): encourages players to build the diplomacy branch of mods too
* But boost influence buildings: more use for high pop planets and influence overall
* Boost morale buildings: ditto and they should become useful again
* Make guns/massdrivers useful - eg. cheap in the beginning, powerful in the end
* Fine tune beam balance
* Nerf missiles very slightly
* Nerf superweapons somewhat: makes the rest worthwhile, while not hurting Evil players too much
* Add new political factions/parties
* Add new invasion types
* Add new hull types (eg. assault ship, destroyer, heavy hull)
So basically a bit of rebalancing here and there to fit the feedback/wishes from a number of experienced players. And then a general personal showcase of added/modded stuff for GC2. I've done this kind of a mod a few times (eg. Battlezone and Homeworld 2) so I know what it takes - time might be an issue, but I could work one section at a time.
1. Has it been done already?
2. Would you play it?
3. Does it make any sense at all?
By the way do collection mods exist for GC2 - ie. mods where the author has used multiple minor mods as a basis. Or do all the minor mods just play so nicely along that you can just select your favourites and put in the whole bunch at the same time?
