Thanks for the feedback ...
Well I'd personally suggest a compilation mod between maelstrom, Enhanced 4x, and Mad Scientist but that has "ultimate pipe dream" scrawled across it.
If you can give a few specific things you like I will consider it ...
On a more serious note I suggest for rebellion figure out how to keep stock races' the maelstrom titans in but have them serve as some sort of cross faction titan like it was design and built before the fracturing began. For Example have TEC rebels able to pick either the Rag or the Maelstrom Titan meanwhile Loyalist can get the Anky or the same Maelstrom Titan.
I like keeping the original races as untouched as possible ... my thinking on this point is that a lot of clever people (Ironclad) have spent a lot of time on the originals ... who am I to mess with them!
I'd also suggest (this is more for the diplomacy version) balancing out the amount of supply cap the titan and dreadnaughts use along with figuring out how to put some sort of hard cap on the number of dreadnaughts a player can have running around at any one time and making sure you can't get titans or dreadnaughts if you don't have enough crews or supplies. It's not fun when a munchkin player figures out how to have 16 cap ships, a titan, and umpteen dreadnaughts along with assorted support frigates and cruisers in an extremely long and drawn out game and they keep putting out another dreadnought every so often.
Unfortunately, currently its as good as it gets ... I've spent a lot of time on this issue as the Dreadnoughts have been in Maelstrom since R1. Others have contributed with ideas and testing. The two real options we have are,
1. implementing them as 'normal' capitals ships (and adding research), with the result that you would possible see 1 (or 2) in a long game (in my opinion ... boring) - referring to AI building them
2. Have them spawn, as currently implemented, and see several. I prefer larger numbers, as the AI can surprise you. Note the reason for the expansion series was to address this issue ... some people don't like the game play. I could bring out a series with (1.) its simple to do ...
