ISLP brings up a good point as he is considering what scales to use for his Alcovia projects.
Let's face it, we love our toys! We love our toys to come in multiple sizes and have lots of them. Many of us enjoy various scales for different gaming periods. As gamers we will fill tables with anything from 2mm tiny models to 32mm behemoths. Some of us prefer plastics while some others prefer lead (now mostly made of pewter). Some of us even break out the plastic toys like Forces of Valor for Ambush Alley style games and plastic dinosaurs to play games like When the Navy Walked, Rugged Adventures or Pulp Alley (coming soon!).
For me I enjoy gaming in a scale that best represents the period I am attempting to recreate or portray. I enjoy 28mm games for skirmish and small rank and file battles such as Sword and the Flame or Battlesystems. For my pure pulp games, westerns and small Civil War games I also enjoy 28mm. In addition, when it comes to using miniatures in my roleplaying games I vastly prefer 28mm to the other scales out there.
In WWII, Vietnam and Modern and Future platoon level games I like to use my tried and true 20mm scale. With the availability of plastic model kids and the massive amounts of 20mm figures available this scale seems ideal. As an added bonus you get to use Matchbox cars for civilians. Need a technical? No problem. Just get a Stan Johansen crew and pick up a matchbox pickup and you're ready to go!
With larger games such as massive battles of colonial or American Civil War, Napoleonics or even Vietnam conflicts I prefer 15mm. I also do my WTNW games in 15mm as well using a massed combination of colonial, ACW and pulpish figures with some sci fi and historical ranges to add that level of steampunk. The benefits of 15mm are that the figures are still relatively big enough to get detail with but still small enough to really be able to do large battles.
For the truly huge games of WWII and Modem tank battles featuring entire companies or larger of troops I enjoy microarmor the 1/285 scale of gamers where you really can set up huge conflicts. Just take a look at some of my vietnam and modern microarmor games posted in this blog and you'll see entire table layouts of massive microarmor battles!
So as you can see I utilize a variety of scales for my gaming. What do you use?
