I just read the very interesting Blog about clipping counters for our games: This strikes me as an absolute must. I started doing this in 1976, and haven't looked back since then. :^)
But there is another, more troubling and maniacal habit I catched: using thicker counters!
Most wargames use far too thin counters, I have a small visual/physical disability and it makes those thin counters far too difficult and aggravating to handle. Tweezers? No sir, I'll never use that!
Some Game Companies do have adequate game pieces, especially Eurogames. OSG, ATO and COA have nice, thick counters. For most of the rest, I have to use the following tactic:
I always (always always always) buy or get another set of counters for all my games. I then glue the extra set to the one in the game, to thus obtain luxurious double-thick counters that are far more easy for me to handle, and that Eurogame feel is unbeatable! Try it for your favorite game, you'll never go back!!!
Of course, it is far easier to do this with brand-new games and unpunched counters; for out-of-print games I had to resort to buying another full copy. To glue two sheets together is not a big problem, especially since the new games coming out have pretty much perfectly registered/aligned counter sheets. Doing this one counter at a time is a bit time-consuming!!!
BTW, I want to give thanks to all the Game Publishers that almost always (but for one notable exception) were able to fulfill my never-ending requests, and continue to send me those extra counters sets. Those guys/gals are GREAT! :-)
