Thus far I've come up with the following:
Writing Prompts: These could be given maybe once a week with a two or three day allowance for people to submit. This gives people time to read the submissions and cast their vote and the winner announced the following week. The submission will be short, however, to test writers ability to convey an idea within parameters, and people won't have to read too much.
Rock, Paper, Scissors Tournament: Like the name says it's rock, paper, scissors. We'd start with eight players in pairs then work our way down to a winner. If it's popular enough more people can join at the begin.
Koiji Bingo: I spent some time trying to work this one out lol
This would probably have to be a monthly event. At the beginning a "bank" will be posted. This bank will consist of words, three word sentences, song titles, names, whatever. Each player will submit a "bingo card" with their choices from the bank. The number of choices will depend on the size of the bank of course. Each day, or twice a day, two or three choices from the bank will be posted until someone wins.
Poetry RP: This wouldn't be a formal RP with character applications and so forth, like the Koiji Balls, people can simple walk in. For this RP however every written word will be in poetry form. All speech, action, thought, descriptions, everything. Not sure how often would be best for this and it's mostly in it's R&D phase.
Guild Story: This idea I got from my college magazine. In every issue a new part of a story is revealed. However, for the guild, member opinion, feedback and ideas will be taken into consideration and the most workable one(s) can be used to move the story along. The story can be about anything, like an original story or whatever. It can be as complicated or as simple as the feedback decides. Probably updated every two months or so to give time for feedback and writing and whatever. This will probably be short.
Cryptogram/Cryptoquote: An encrypted message will be posted and the first to decipher it wins. In the puzzle one letter of the alphabet is substituted for another until the real message is revealed.
Eg: Yee daaw zbhqdl jacu za zbalu tba tyhz
Answer: All good things come to those who wait
This can be used for famous quotes, random lines from a post by a Koiji member, etc. I figure really long and difficult puzzles can be given a month to solve. Easier puzzles given for a week or what not.
Koiji Jeopardy: I have a Jeopardy program that is similar to the actual game however, it has only one regular round and the Final Jeopardy round and allows up to eight players. In other respects it much the same. It has categories at the top and point values can be assigned and so on and so forth.
I'd post the images of the board as the games goes along (so that I wouldn't have to draw one from scratch xD) as well as the answers, questions and points.
Koiji Scavenger Hunt: Gaia has random Gift Box thingies and I thought to use something similar. However, we can't embed the located items/clues into the forums as user bop around so one idea was to RP the whole thing ^^
An area map will be drawn up for the players to use. Clues are determined by difficulty and when someone finds an object or whatnot they must be able to describe it and it's location. Based on the clue they may know that what they are looking for is an eraser, simply stating that doesn't mean that they found it. They have to actually go to/search its location and describe if the eraser is on a pencil or one of those block ones.
(There will/can be simpler hunts ^^)
----- I also wanted to use the games that were already in Koiji along with these calendar events. For example, during Christmas Bingo the bank would contain elements that pertain solely to that season. Word Association will use only Christmas terms, the same can be done for the Guess The Quote Game, etc.
----- Whatever doesn't work can be dropped or less frequent, no worries about my feelings lol. Whatever does work it's frequency can be bumped up.
All these are still in their development stages, most of the kinks haven't been worked out as yet.
I'm opening this up to feedback from the entire guild about what you guys do or do not like and any ideas you may already have. If you're shy and don't want to post your ideas feel free to send them to me via PM ^^
