Quick question... Can't find what to mod...

Well, I'm no modder but I would hazard a guess that you could create another ship class in Vehiclesizes.txt. As for plagues, I haven't a clue.

Define class of ship.
If you mean simply a new size of hull, then yes, VehicleSizes.txt has everything you'd need to modify.

However, if you mean changing the Ship, Base dynamic, then no. There is currently no way to do so.

You can, however, add in new types of units via the VehicleUnitTypes.txt file. You'll allso need to modify or make a related hull size in VehicleSizes.txt. Both of those files are found in the Data folder of SEV.
I believe THIS THREAD tells you how to make completely new types of units. It uses a Militia as the example. it allso describes how to cause the AI to use the new unit.

I, sadly, dinnae know how to change Plauges. The people who might are Captain Kwok, Devnullicus, and Fryon.

I'll make one later.

You can't change how plagues work, but you can add extra levels of plagues in DamageTypes.txt, found in the data folder.

Do plagues spread (by migration I guess)?

Plagues do not spread.

It sounded like a good idea.

It would be possible to make them spread via a loop in the Events script though.

It is a good idea. Would be a nice feature, to have a plague run rampant through some of your systems if left unchecked

I believe it worked that way in MOO. Ships in a plague system should also be affected.

Seriously, you can add more plague levels? 8O
Level 5 plagues are deadly enough already - I wonder what formula Aaron's using to compute plague damage...
