Requirements:
Fun grind [or not much of one]
Fun for all levels [1-xxxx]
Good economy
Decent graphics [Not like runescape]
Minigames

Games ive liked:
Puzzle Pirates - Good economy, minigames,
Flyff - Good economy
Runescape - Good economy [shitty trades though]
Endless Online - Easy to manipulate economy >:] but too much of a grind.

Wonderland Online Might Be Fun For You To Try.
Leveling Is Easy Once You Know How.
Entertaining For All Levels. (Different Quests, Pets, Equips)
Economy Is Ever Growing, And Completely Manageable To Buy & Sell.
2D Graphics, Yet Entertaining.
There Are Afew Mini Games. But Mainly To Progress In A Quest.

I'll try it when i have time =P

DAOC

mabinogi!

where it actually is based on more user control than i am lvl xx so i can kill lvl yy monsters
and yes almost all into community for economy very little based off lets buy from npcs and when i dun need it i sell it for cheaper (gotta make or find the better equips) - can equip anything at lvl 1~ though just cause u can equip anything doesnt mean that ur god, might still die to low lvl creatures~
not ur typical mmo for sure. grinding is alright depends on ur lvl for sure since higher lvl = stronger attacks but even so, lvling is not too bad given that u even get free rebirths every 3 weeks (reset current lvl but keep ability points and skills, not stats though, just to lvl easier)

Runes of Magic.

Not sure about minigames cause I haven't been playing that far.

If you dont mind the 2D shit,
Maplestory FTW!
