https://gitlab.com/alexwbc/Rize-at-Zero-prototype/blob/master/DRAFT_DESIGNS/riseatzeroGDD.odtThe bountysource currently lay at 0$ (sorry, couldn't add found by myself, but people may find the concept interesting enough to provide some?) How works BountySource is that money are given only if the one who actually put the money are satisfied: no middle man. The idea is there draft be me, but who and when money go is ultimately a choice of those who found the prototype.
This concept is relatively new: it focus strictly on core element of survival through cooperation between player. All player are against the environment: you can't simply "play your game" and ignore other player (lemming-like newbie mostly): each time a player dies, the difficulty scales up to insolvable situation. Its not about (as player) your own survival, failure to cooperate and use (partially private/partially shared) resources ends the game for everyone.
