Totally, especially when I've just got new pieces or there's a new v-set just out. I normally can't be bothered setting up a whole map for playing by myself, so I just play this little game where I put two teams of four pieces opposite each other, set up on my playcase. So it looks like this:

XXXX

---

YYYY

Then they just run in and smash each other. Obviously some pieces and factions are much more effective in this type of game than they are in an actual game. For example AniStap, QGJ Jedi Trainer, and Ferus Olin is a potent combination in this format - if you can keep AniStap alive long enough to go round for a couple of strafes, he can be devastating. But it's actually pretty useful for practicing decision making, and figuring out what pieces you like to play - normally most teams do have around 4 main attackers, so you can cut out all the little tech pieces and filler and just have the meat of each squad going at each other. Obviously it favours some factions (for instance it's difficult to keep Nen Yim safe if you're playing Vong), and winning the first initiative can be very important, but it works for me.

i often do . I work 3rd shift so for me we only get to play once or twice a week, and on weekends i am up late any way so a few matches is always interesting, pluss a good way to test out squads before taking them to a tourney

I couldn't. My bad sportsmanship would lead me to murder the lying, cheating swindler I was playing.

must have been the weighted d20!

I'm having a logic error when it comes to simultaneously revealing reinforcements.

side note: every time I look at this thread, the word "by" comes to mind and my mouse hovers over the edit button...

I have and the only way I found to play competitive is to randomly choose factions with a die, then randomly choose a team build with a die (I.e. Swarm melee, beatstick ranged, stealth mixed). Then either play the best you can with each team or randomly choose a personality (aggressive, defensive, divide and conquer, etc...)

Any moves that you are unsure of roll a die and see which way the character moves, up or down, left or right. Which piece to attack. But the random team picking helps a lot.

If god intended us to play with ourselves, he wouldn't have invented vassal.

Also cuz it sucks setting it up...

yes but what i found was its more fun using mostly melee based armies because ultimalty the strategy is to get adjacent then let the dice do the work. figures without melee, and have Twin GMA Evade and so on, are harder to play unbaised because they have more movment options and ducking and hiding and so on.

I do all the time, sometimes twice a day. You know the wife just can't keep up with me.
I also play SWM by myself on a regular basis.
