25mm is easier to detail than 12mm or 6mm, some miniatures are less or
more detailed than others. Again, this is much a matter of personal
preference and what you want the miniatures for. Look over as much
as you can before selecting starter miniatures, unless you have your
heart set on something. Just don't pick something so fussy or detailed
that you'll get frustrated with your new hobby on your first project.
Also, refrain from doing that `special' one until you've had a little
Some offerings of types in the 25-30mm range are:
Citadel: tend to have large areas and broad features, and
are recommended `beginner' pieces if you can't find something
better. Once you have the feel of painting, can be masterpieces.
Heartbreaker: Everything good about Citadel plus some of the most
excellent modelling ever done in this style of figure. And costs
Metal Magic: again, heavier features, thus good for the novice.
Mithril: pre-primered and a little above 25mm, broad detail
Ral Partha: tend to have sharp detail, good once you have the basics
Grenadier: detail can be hard to follow, but that can be a plus.
Soldiers & Swords: Good variety in both individual figures and
quality. Some are excellent, some aren't worth the purchase.
Simtac: Good figures with fine features and nice detail. A little
difficult for the beginner.
Various military miniatures: varies greatly, use your own judgement.
