IDEA: The alliance request feature used in-game is updated to allow you to specify levels of commitment. At any point, a player can still break an alliance, but if he/she breaks the terms of the accepted level, this will count towards their public TURNCOAT statistic (the % of alliances that they've broken). The TURNCOAT stat will let other players know how trustworthy they are.
[NOTE: These levels are just suggestions. Feel free to suggest others or different approaches]
"This idea demonstrates a lack of understanding of the actual game of Risk..."
Samh, I just wanted to clarify a few things here. We worked with Hasbro for over a year when we developed RISK: Global Domination, dissecting every rule from their 1993, 2003, 2010 releases plus other variations. We distilled this down to what Hasbro considered a "classic" version of RISK. So, rest assured we are very familiar with the actual game :)
Hasbro has released multiple board and gameplay variations of RISK and continue to iterate on the core rules, including the notion of player alliances. For example:
What Hasbro has done so well with RISK over the years, is to preserve a total respect for their classic and beloved version(s), without ever remaining static. They've pioneered really creative adaptations of the game, for example the evolving rules and deliberate player customisation in RISK Legacy (where players are encouraged to tear up and dispose of pieces and write their own rules into the rulebook).
In this spirit, we are looking for new ways to further evolve alliances (and many other aspects of gameplay) into something more meaningful and appropriate for RISK on mobile. We've received many requests from our player community on this, which is why we set up the forum to give everyone a platform to share and discuss.
We have total respect for your perspective here, but we believe that, collectively as game developers and players, we can add something new and meaningful to the RISK canon without diminishing the game. This concept is just a starting point, so everyone is welcome to pull it apart and add new suggestions. –Lee@SMG
