I think I'll probably play mostly single-player, but I tend to do a bit of multiplayer with friends.

I gravitate towards FPS's like TF2 for my multiplayer needs. I can hop in, do my thing, make some gibs of my buddys and then get on with life.

Its difficult for me to commit large portions of time to a game without interruptions. Kids and all... really kills the multiplayer experience. And saving a game to come back later never really has the same magic as playing through to the finish in one go.

So, yeah, Sins will probably be just a single player game for me. (But a great one)

Both!!!

If game is great - then it deserves attention on all fronts

Both.

i would but once again time is always a big constraint. IF there were lots of tournys when i would KNOW what times and how much time i could commit then i could play lots more multi.

Also it takes so long to start a game (people not on) that by the time i start i have to leave halfway through.

Multiplayer right from the go

There is a third option people forget - LANners who are half/half

I like the idea of playing a singleplayer game that lasts for a month

multiplayer mostly, I dont care how good you create an AI its never going to have the adaptability of a person. at least not until you find a way to get rid of heat into microsinks in order to drastically reduce computer structure, but thats another topic entirely.

Definitely singleplayer. I generally lack the patience -- and even more importantly, time -- to play against other people, regardless of what type of game it is. With SP, I can play according to my own schedule.   

FYI for those new to the game:

-There are smaller maps in the lastest build that take much less time to complete.
-There is a multiplayer save so you can pick up a larger game later on.
-Playing in teams can speed up the game considerably.
-Play locked teams with a friend against a small number of AI for a quick game.

the biggest obstacle towards quick multiplayer now is people's adamant adherence to the crappy strategy of turtling. while it may seem initially effective the person who runs around offensively grabbing from other people will eventually outproduce you, and then will proceed to beat you over the head. thats even IF they have to fight on multiple fronts at once. (esp if they are vasari, can you say phasegate banonza?)

and thats where you're wrong...
its not rushing at all! its just guarding against any sort of stagnation of the defensive lines, if you try to remain behind a wall of turrets I will outproduce and smother you! likewise in games where I've tried to hide behind a wall of turrets I've been soundly defeated.

its not "rushing", that is simply not possible in sins. its about making offensives exactly like in any realistic war. If you stagnate you hand off initiative to your opponent, flow and battlefields are then dictated by him, and you will just have to be lucky if you even have a fleet in the right place when he bears down upon you!

trust me, I used to want to turtle. I still do! but its such a nasty propensity that causes you to fall quickly behind your opponent, you simply need to switch mindsets.

Having played a few singleplayer games and a few multiplayer games now I have to say I'm hooked on multiplayer. I doubt I will play singleplayer much at all, maybe just enough to crack the new ai and test out early builds.

On the time issue, is a 1 hr game so bad? I would never play any other game single player for less than an hour anyway, usually I'd spend more time if playing alone!

On the rush vs turtle issue, fair enough if you turtle you'll probably lose in the end, but rushing isn't the same as in supcom etc, where every half-second counts and your brain hurts at the end. I think it's worth at least trying out multiplayer, even if your experiences with multiplayer rts games generally have been negative. You don't have to literally rush, you just have to keep pushing.

In this game more than any other I've played the politics between players add real depth. Everyone is out for themselves but if you don't find a way to negotiate you will surely lose. This is something you'll miss out on with singleplayer.
