Winterfall is a sandbox RPG influenced, gameplay-wise, by experiences as diverse as Mount and Blade, Mass Effect, DayZ, The Sims, the Elder Scrolls games and, of course, the latter Ultima games (7, 8 and Online), set in a fictional late antiquity/early dark ages setting. Contrary to most RPGs where the player is in control of a single hero character from beginning to end, the focus of Winterfall is on a House, or Household, which is grown and developed through deeds performed by the player's successive characters.
Lush and dense environments should feel easy (and desirable) to get lost in, as though something unexpected can lurk behind every tree, every rock, and beckon the player to always explore one step further, in sheer search of adventure.
