So here's what I can give you about the game, and I'll do my best to answer questions (I am not an owner but yes I am involved with SodaPop). Understand that all info here is subject to change.
SDE is being developed and tested and was demo'd at GenCon and PAX and I will be running demo's at TheWarStore Weekend as well. We have plans for other con's including some in the EU, but until details are hammered out, I can't tell you which.
SDE figures are not in current release, the figures sold at GC/PAX are our demo sized figs, so they are about 20% larger than the production pieces. All the models are built in 3D and rapid proto'd for the masters. The current line which will become available in waves is thus:
Kobold Soldier - 3 for a playset
Kobold Spearman - 3 for a playset
Kobold Slinger - 2 for a playset
Kobold Ironshield - 2 for a playset
Kobold Mage - 1 for a playset
A playset is what we use to run our demo's and what is currently the selection of what we will package (I do not know pricing yet and it is subject to change).
About the game itself - it is the 8 bit dungeon crawl we all loved when we were younger wrapped up into a mini game. The game is played on an 18x18 surface. One player takes the heroes, the other the dungeon. The game is scalable so you can have more than 2 players at a time. The dungeon gets a portal (spawn point) for each hero taken. Heroes explore the dungeon, kill monsters, get loot, hearts and potions (not necessarily all at once though) and search for treasure chests.
As the game progresses the power of the heroes grows as they gather loot and kill monsters, but the power of the dungeon increases as it does damage to heroes, going from 8 bit to 16 to 24 ultimately leading to boss battles and the 'final fight'.
There are expansion packs planned, new monsters, new loot, new heroes and new dungeons as the game moves forward.
On a personal note, I learned the game in 4 minutes and love it every time I play. It's easy to learn, fun to play and easily replayable.
