The players will explore abandoned and overrun ruins, and reclaim them for civilization.
Don't need a new system? The game includes 6 lairs stocked with monsters, ready for old-school play.
What makes it different than other RPGs?
The GM rolls all dice during play.
All PCs are fighters (with some ability to cast magic)
Spells are typically cast by reading a spell scroll
There's no gold and no gold economy
When a PC's Hit Points are reduced to 0 or less, the PC is not killed or knocked out; he or she is sidelined. A sidelined PC is still conscious and can grant bonuses to other PCs, but cannot attack for the rest of the fight.
The party levels up as a group, not PCs individually.
