What do you use for keeping track of opened and closed doors? Blown open doors? Poisoned and other status markers? Holding your cards? Keeping your minis? Checking for line of sight? Gambit? Rounds? Storing maps? Force points and damage counters? (for anyone who doesn't have enough official counters)

Here's what I use for them:
open door: blue 2x1 lego brick.
closed door: red 2x1 lego brick.
blown open door: blue 4x1 lego brick.
poisoned: I try to remember!
holding my cards: just a simple rubber band!
keeping my minis: in a lego bin.
line of sight: a thin long rubber band.
force points and damage counters: lego bricks and studs.
keeping my maps: a flat file.
(nothing for gambit or rounds(I don't usually play with gambit))

(as you may see, I'm more than just an SWM fan!)

I'll be looking forward to seeing what clever ideas are out there for keeping your minis tidy and organized.

I just remember which doors are open and closed
Line of Sight, pretty much anything handy, usually a card edge if it's long enough.
Force Points and Damage Counters: D6 for Force Points, and I have a buttload of damage counters from various starter sets (including Dnd minis and SSB). Face-up means 10 damage, face down means 20.

how primitive
might as well use bear skins and stone knives -LOL

you'll see at GenCon my awesome methods

Wish I could go...

I'm sure you've got some LOS machine, mechanical damage counters, a steel case for your minis, and a book full of laminated cards!

open door: d6: 1 showing
closed door: d6: 5 showing
blown open door: glass bead
poisoned: I try to remember.
holding my cards: card storage boxes, sorted by faction
keeping my minis: storage boxes (3 toolbox type and 3 craft types)
line of sight: a retractable thing-a-ma-bob
force points and damage counters: white d6 for FP, red d6 for damage

You didn't ask, but we use d10s to track gambit and a d8 to remember the round number

I laminate my maps,so I can just use a dry-erase marker and mark down which doors are open/closed. I also have clear plastic sleeves for my cards, which I can write on with dry-erase markers to take down damage and such. Makes it super easy to keep track of force points. I usually just eyeball the LOS, but if its close i'll go grab a straight edge or a piece of string; Whatever I have laying around.
I keep my minis from RS and CS in a dual sided tackle box, and the rest of my minis I keep in the RotS Starter Game box. My huges are kept in various old booster boxes. My cards are in a three-ring binder with those clear 9 card pages. Pretty easy to flip through real quick and pick the cards I want.

I started playing minis back in the Rebel Storm days and and have always played super casual games. No counting rounds, no gambit or any of that. Deathmatch all the way. It keeps someone from just going and locking them self in a room with override, and can make some very intense matches that come down to initiative rolls. Fun times

Oops. I messed up on that demonstration up there. I fixed it above.

Biggsy, those door tokens are cool! Where did you get them, are they from another game?

I think dice is so much easier. The counters are rather fiddly.

Yeah the tokens are cool, right?

I ordered them from LITKO Game Accessories, an awesome supplier of game tokens, markers and lots of other cool stuff. I highly recommend their products.

Here's a link for the blast tokens

The other two are conversions of the Flanked and Defend tokens. They have other customizable tokens, so i just contacted them asking if i could order some of these with "open" and "closed" on them instead. They were very helpful.

I use the tokens made for the game XD
