I had a good one last week. I was playing with dolynicks SG Races mod. I was the Asgard against four unfair/agressor Wraith AI's, locked on the same team, in a sytem i made myself ( five clusters of worlds, each even in resources, connected by one phase lane each to a central ring around the star. Between each cluster is a super-duper pirate base, so there are 3 ways int each cluster. Lots of starting resources too, so you get to war faster )

Blimey that was fun. I had four of the Ragnarok super capships and six Odin battleships, and my defences of the centre-ring chokepoint, against 60 Wraith hive ships and about 200 of there cruiser class heavy carriers and battleships. Got real dicey for a while. Fortunately, the Wraith dont have shields, so no mitigation either and the Ragnarok gets an AWESOME anti-fleet ability (way better than MB)

It fires twenty blasts at targets in range, doing 1000 damage. Each one of these blasts propogates to 20 more targets, doing 500 damage. Then they propogate to 20 more targets (including strikecraft) doing 250 damage. Aptly named "Decimate Fleet"

Anyway, by the end, all 60 hive ships lay shattered and broken. One of my Ragnaroks was dead (the "Apocalypse", at level 10), and at 16000 hull and shield she is a tought kill. certainly an expensive one at 25000/3000/2100. All of my Odins had gone from level 2 to 10, and they proved to be the battle-winners.

After that, well, it took me a while, but the enemy fleets were all broken and dead so it was mopping up. By the time they resurrected their fleets, one of the AI's was dead and id maxed out my fleet with the awesome Mjolnir heavy cruisers, and a few Freyja motherships to round out the caps. Theywere unable to mass anough of a fleet to destroy another of my Ragnaroks, and it all finished in an impressive, but futile, last stad around the last AI's homeworld. Lots of ships going BOOM at once
