I love your idea but i think it should just be gambling, there is probably young kids on this game but they probably have the swear filter off and i don't think gambling a in game currency is bad.....at all.
But here is one of my ideas(dont take thread off topic i hope)
They add a "Bar/Saloon" (like ur arcade name with a more westerner theme base) when you walk in the saloon/bar there is tables everywhere almost like trade tables but with different designs, also on the bar table buy able food and drinks like bread and beer(you already can buy beer in game, so beer is not bad) and when you walk up to a table u can grab it, basically your idea but not "go fish" lol that sounds to childish and i know that you gave it that name because yes there is kids on this game but lets face it, i think we all know that not a lot of kids play this game, (there is only like 300 people that play this)but anyways when u grab a table like u said there is credits(or just use or gralats) and then the more gralats or credits we put in give us a higher chance to win so say there is a 500 gralat table and a 1000 table, everyone that joins the 1000 table(maximum of like 5) has
to put down 1000 and you have to put 1000 to play(no putting above 1000 though) no putting above 1000 so everyone odds are fair, it spins a wheel or does some random thing and the winner takes all but it does the same thing for every table (no matter what the amount of gralats is) also there should be custom tables where you can rent
a table and choose how many players can join and the amount of money you wanna put up... say you and your friends wanna bet 100k gralats and you are both feeling lucky, you can buy this table and choose 2 people to join and your friend joins then u can do how ever much money you want, but to join however much money the person says they wanna do it for you have to put in before you join so u add money then u get in. there should also be a watch option so if someone is doing a huge bet everyone can watch and there should be like a leveling system so people know the #1 gambler, in my opinion west would be the best server if they added this in but i am like 80% they wont because they dont want us to have fun and i just wasted 5 minutes of my life typing this, oh well but last but not least these tables should be in bases, so while your basing you and your gang members can gamble instead of sitting there doing nothing,
STAFF PLEASE CONSIDER THIS
(great idea night)
