OK, the game was online(and u could play with other players)...it was a card game and had 5 heroes and 8 officers(i think so?) there were blue, red and green cards (knights orcs elves wolfs etc.) You can fight with an opponent or an A.I. and if u collect 3 green,red or blue cards(or all 5 heroes or all officers) - you cast a powerful spell.
Sorry for bad English.Please help me find my game(i want to play it)
everything except the 5 heroes and officers sounds similar to Magic: The Gathering... but otherwise, no idea what you might mean. Try www.abandonia.com and looking through their database to see if something strikes you as familiar
