The DS has about one high profile game coming out evey week through the month and beyond. It is actually a pretty good idea, although it can put a hurt on the wallet.
Resident Evil DS and Rub Rabbits this week.
Age of Empires which has received good reviews comes out next week.
Super Monkey Ball the week after and then Princess Peach the last week of the month.
I know Tetris comes out in March as well as some other games. (Worms/Metroid)
I have been buying games for a long time now and the DS has continued to crank out the good games week after week. I hope there is a dry spell in the near future so that I can get caught up on all of the games.
