Hi,
Because people are always asking about this kind of thing, I thought I would share the solutions I have used so far in protecting my AH gaming bits and pieces. The tokens part needs fleshing out because I am yet to find an answer that I like - or enough advice to be able to implement one of those options! I hope this is of some use, to somebody:
Sleeving Cards
*****************
I use the FFG cards. They are nice and sturdy and guaranteed to fit. I originally tried some of the much cheaper Mayday sleeves but found them to be horribly flimsy. However, Mayday now do Standard Chimera and Chimera Mini size card sleeves, and although they are flimsy, they fit tightly enough so as it isn't going to matter. A pack of Mayday Chimera sleeves is cheaper than FFG sleeves and contains twice as many (100 vs 50). Also, thinner sleeves keep the physical size of your deck down; a stack of FFG sleeved cards is way bigger than a stack of Mayday sleeved ones. I have already sleeved too many cards FFG. It's too late for me to turn back. Maybe you can still be saved before you reach the point where you have paid more for FFG sleeves than you did your house... Still, the FFG ones are nicer though.
(1) Ancient One cards (Mythos cards, Gate cards etc.)
*Fantasy Flight Games Standard American card Sleeves (the green ones, come in 50s)
(2) Investigator Cards (Spells, Common items etc.)
*Fantasy Flight Games Mini American card sleeves (the yellow ones, come in 50s)
(3) Great Old Ones and Character Sheets (the massive cards)
*Genuine large Polyprotec large postcard sleeves 7 x 5 inch (came in 100)
Do an ebay search if you struggle. They are sealed on three sides and don't have a thumb hole thing. They fit pretty well and offer good protection. They do have a visible edge to them on the three sides where they have been put together. Ultra Pro do offer similar things, but according to my research they are either really, really chunky or thin, like comic book wrappings. So I opted for the above.
(4) Heralds
*Genuine large Polyprotec large postcard sleeves 7 x 5 inch (came in 100)
FFG, realising that the 7 x 5 inch cards weren't challenging enough to sleeve, cunningly opted for the bizarre card size of 4 1/2 x 6 3/4 inches. Brilliant. They don't fit very well as they move about inside, but it's the only sleeving solution I have found, so far.
Stands
********
*I use the stands from Tomb: Cryptmaster (by AEG)
It's much nicer to play Arkham Horror using stands. I didn't originally because the stands included with the game have nasty, sharp teeth that will slowly devour investigators and monsters alike. Solutions suggested to me have been to engineer your own stands (folded paperclips?) or to file out the teeth on the stands that come with the game. I recommend getting hold of some of the stands from AEG's Tomb, or Tomb: Cryptmaster. I contacted AEG and asked them for some extra stands that I could use. Their stands don't have teeth and don't compress the tokens. They just hang on by friction. AEG kindly sent me out a batch to use - free of charge! And when they didn't turn up they then sent me another batch - again free of charge! I now have enough stands to prop up my monsters, gates and investigators. AEG rock! I don't know why FFG don't offer alternative, non-damaging stands, but this was the best solution I found so far.
Other sources may include (I can't vouch for these):
*The original, 1985 Arkham Horror (had a different type of stands, apparently)
*Star Wars: Jedi Unleashed
Tokens
********
To be honest, I haven't got as far as working this out. Possible solutions that people have suggested:
*Print your own tokens to degrade in lieu of the proper ones (a lot of work!)
*Sticky backed plastic (don't know if this would work as the tokens are very thick)
*Varnish the tokens (haven't tried this)
*Use a PVA glue mixture to seal the edges (haven't tried this, but it would only protect the edges)
*Roll dice against a chart to randomize the monsters instead of shuffling them (I didn't want to do this as it would alter the probabilities and be a pain)
P.S. Forgive any typos, it is getting late...
