I played a test game of Frostgrave yesterday with a few mates, one of them acting as a "wizarding instructor" of sorts (a.k.a. he explained the rules to us).
I won't do a full write up, if you want, you can read more about the game on Gunbirds blog. Suffice to say that I'm sold, this game is fun!
We both opted for a "loot and scoot" approach, instead of trying to take out the enemy warband, so we ended the game with only 3 casualties (and a near dead apprentice, due to failed castings...).
So, I'll definitely be doing more with this game, I'll just have to see how to fit this into the greater Questing/Chivalry/Dungeoneering project(s). I won't be building a full set of snowed-in ruined city terrain, as I've more than enough scenery projects to build/complete for my fantasy gaming as is, especially now that I have a village worth of civvies and livestock. (There's dungeon terrain, a dread forest, a medieval/fantasy village, maybe some caves and a castle... the snowball keeps rolling. Step one is a storage solution, though, no use building it if I can't store it safely.)
I had already decided that my, loosely defined, setting would incorporate a dark mysterious forest (a classic chanson de geste/chivalry romance trope) and a "Coast of Lost Cities": A long stretch of deserted coastline filled with ancient, ruined, cyclopean cities that extend into/below the waters of the sea. Probably millennia old and riddled with subterranean catacombs, no-one knows what race built these cities and if they are partially submerged due to the rising of the seas or by original design.
Oppressive and inhabited by all sorts of monsters and creatures, people avoid living close, but at the same time the hidden treasures and promise of ancient knowledge attract adventurers and fortune-seekers by the droves.
Either would make a good alternate setting for Frostgrave games. So, for me, depending on what I build scenery for first, I will be playing either "Waldgrave" or "Ruingrave".
Plus, wizards could have many reasons to clash in other locations as well. Maybe they need rare ingredients, leading them to raid a Griffon breeding ground, or they raid a village for youths with magical talent, they may both want to recharge an item in an ancient henge... Or they're just feuding over a border town between their respective territories. Or one wizard raiding another's supply caravan. Plenty of reasons for a magical showdown without needing to loot some dilapidated old place. :)
I need more wizards, though.
