What floats your boat...
I mean, what kind of situations/little things do you like in this game? What brings you most satisfaction?
...is it the constant push or being pushed from the early seconds of the game, feeling the thrill, where you almost do things instinctively, as there is rarely enough time to think whether to upgrade this or that?
...is it watching your income rate to hit 200 credits per second (while the others dont have even half of that) as you just set up some incredibly large trade-network?
...is it zooming around your perfectly fortified world with 2 starbases, shitload of hangars and repair platforms and mines?
...is it watching your empire to span across half of the map?
...is it bombing enemy homeworlds?
...or how about screwing around with your Titan, leveling it and then deciding, whether to put points into this ability or that one?
...or is it something completely else? Dont keep it for yourself
Personally, ive found out, i have most fun, when i am actually losing, but still somehow manage to survive. And its not just Sins, i recall one game of Generals:Zero Hour i played few years back with my buddies, where i was on the verge of defeat, had my base leveled by enemy tanks, only to escape with few dozers to allied base to rebuild there and finally killing about 20 enemy Overlords by single MOAB bomb!
Similarly, i played Rebellion last week with my buddy against 2 AIs...and we were quite beaten, well especially he had hard time and as i was trying to help him out, i found myself to be overrun by TEC Rebel AI, which i could handle until that point quite fine...it even threw a Ragnarov against me, when i did not even had Titan myself. It looked pretty bad, but as i played VLs, for the probably first time ever, i was actually "forced" to go fully mobile, as i simply could not hold my planets against the waves of AI units wreaking havoc at every single one of my planets. So i stripped the remaining ones and took Vorastra with all the capships i had shortest route to enemy capital planet, bombed it to death, colonised, stripped and for the money summoned some nice reinforcements via Dark Fleet Beacon. Now that was fun!
BTW, i saw people comparing the "VL Death Fleet strategy" to Battlestar Galactica fleet, which is quite fitting, but actually i see VL more as Cylons. Vorastra being their version of a Cylon colony, actually even cooler and better looking.
