the two things that i feel definately need to be implimented first would be to be able to see who is online in your games so you don't wait around for someone to play their turn who isn't there. also, the creator should definately be able to set a time frame for each turn. i like 12 hours as standard but can be adjusted up or down.
i don't know if this has been suggested, but i would like to see a partial randomizer. i've played too many games where certain players have a distict advantage at the begining when they have either the whole territory or all but 1 country in a territory. i call it a partial randomizer so that there would be a ratio of countries per territory that a player can hold. i like no more than .5 or 50%
rt games are popular. i player a couple myself but they are hard to regulate. i would like to offer a suggestion to add rt as a game option that will show on the games list so there is no mistaking those who want to play rt. also, in the specific rt games, a player who exceeds their time limit once should be considered a deadbeat in an rt game and ejected. to protect points and cheaters, i would say that if any player in an rt game is ejected, it will be a "no points" game. the fun of just playing rt is still there.
i think the feedback feature is great! i would also suggest though that there be a system that someone can challenge negative feedback and mods are available to review the game, what was said in feedback, and the argument in the challenge. it's too easy for anyone to leave frivilous negative feedback.
i would like to see a feature in the future where you can play against ghost players for no points. this will allow rt games and will also allow for practice games on new maps or maps people haven't played on and would like to see if it's for them in the real games for points.
i am going to have to kill myself later for suggesting this. i like being able to play 4 games at once for free, but i have been here long enough and played enough games to suggest that you decease it by 1 or two games(to 2-3). it will encourage more players to pay. i say this because i love the game of risk and i was lucky to have found you guys. i feel $20 a month is more than fair to have fun for a year. i want to see people who use this system to consider paying for premium membership as i am. for those who can't afford it or are too cheap or like to just get things for free without giving, they still can play a couple games at a time. also, by decreasing the total games one can play at once, you decrease the number of deadbeat players playing. you would also decrease the ratio since you are increasing the ratio of premium membership games. the games that will hold less deadbeat players.
another suggestion on memberships, i would like to see 1 free week of premium membership for those who have "qualified" as a non deadbeat. it will let them see what is offered and i believe after that trial is over, there will be an increase in paid premium memberships.
last but not least, i love your site! everyone has something in common here and i sense sometimes a feel of a community. way to go! after playing for a while, i finally decided to browse the site more thouroughly and decided to give my time and input. the only real negative thing about this site is that it takes away your time to do more important things in real life hahah. i'm serious when i say i have to sneak away behind my wife's back just to play sometimes

p.s.- if you need more help overlooking games and feedback, lemme know what i can do in my spare time to do my part to make this place even better(if that's possible). or even to just brainstorm for more ideas....
