Lol Doom is 50 years old and 2d sprites. For a game that has been ported to so many different systems it had better run smoothly.ÂAnyway BiA was an attempt to do something FRESH and push the system to the limits. All games have bugs but BiA was still a major achievement.
There was nothing fresh about BIA DS since it's BIA is already available for high end cell phone and it look and play just about same as DS version. BIA DS is developed by Gameloft which is known to develop cell phone games, I doubted that they to push the limit of the DS by porting the cell phone version over to the DS.
