This is a game I used to play that was like a platform launcher. It had an extensive game library of games you could launch from single player to multi-player. The game in particular and the reason why I picked up the platform was the yu gi oh game it provided. The yu gi oh game allowed you to move a chibi like avatar and walk around in the world. You would initiate duels by clicking other player avatar and requesting a duel at which point both players would need to find a place that the duel could take place because of the in game mechanic that used a duel disk system sort of like the yu gi oh anime series duel city that Kaiba developed which was something that the game also mimic in game. There was a Kaiba corp in-game that kept track of a leaderboard (I think). Anyways I was hoping someone might have played this game and remember the platform it came from. It was definitely a pc game and not a yu gi oh strictly game. Like I mentioned, the platform had an extensive library of games it could launch.
