A card game could be an interesting concept, especially if, using the Pokemon idea, you had to collect the cards to play with and they were actual items!
Maybe buy a starting deck thats themed in a Mene characters interests or themed with all the mene characters. And more powerful cards were only obtained by doing quests within the site or through gifts from certain characters you played against.
Itd be a nightmare to create and code i imagine, and add even more work for the already over worked pixel artists if some cards are actual items you can collect.
Unfortunately, i dont see this happening any time in the near future though because, as Jelly stated
here, there just arent the funds available to create new games and such.
