Hmmm, I have been using World Works for about two years now, first for wargaming, later for RPGs and to hand out finished models as prizes for events.
Very nice,
The Maiden of the High Seas is my favorite of the models, and also the hardest that I have built. It is 140' scale from stem to stern, dominating a table top quite nicely.
Castle Works Ultimate is my second favorite, though I have to date only built one model that is (almost) entirely from this set - a Wizard's Tower that somehow changed from a Wizard's Tower to a Navigator Mage's Lighthouse...
Legend of Skull Cove and
Arena Works vie for third - I use Arena Works for Mordheim, which means that it gets pulled out about once a week or so, Skull Cove sees less use, but has so many nifty pieces... and with the new King Kong coming out I have this strange urge to use Skull Cove for Skull Island...
Be warned, the above pages contain animations, and could take a while to load - but the animations are worth watching.
The Auld Grump
*EDIT* For those who sense a nautical theme to my gaming... you are right.
I am currently building a new Arena Works set, which will have a water insert for 'naval' battles in the Arena. (Hey, the Romans did exactly that...)
