It could look like a space station and when you click on it's picture it acts like a game within a game...
Say I found this encounter called "Space Station", clicked on it. A screen pops up, it has a few options like: SHOP, Gamble, and VIP GOLD.
-SHOP contains:RARE Items you can buy or sell, special avatar pictures, buy banners and etc...other player designed, and etc for in game credits or CP.
-Gamble contains: card games, board games, and slot games:each with a different set of credit bet limits....
-VIP GOLD contains: extra bonuses for gold members such as: buy SP or AP items for ship designs, get enhanced gambling high-bet gambling games for gold members, and etc...
-Crafting area....
-and many additional possibilities can be extended onto to the "local space stations"....endless possibilities....
Oh concerning how Blackjack "is so easy"...first of all I never played blackjack but I would suggest easier games have smaller rewards where as harder or more random chance of winning games pay out bigger....
PS: the nice thing about having it the way I suggested as separate rooms/areas in a space station is you can set limits or age requirements.....PS: age required areas would ask for a players info before use....
Gambling area: could be split in to 4 areas<
1.)UNDERAGE GAMES -games not casino related...(emi and others could use other "flash games" as the basis....)
2.)VIP UNDERAGE GAMES- underage gold members only. They can place higher bets on games that are found to be appropriate for their age bracket. (give more a selection)....
3.)OVER 18+ games- casino games and such normal limit bets based on probability of winning
4.) VIP OVER 18+ - must be gold members and must be over 18. Higher bet limits. (Maybe a slightly better chance of winning a little overall)
