I edited the main post yesterday I found a few errors and counted mario kart twice, there are only 92 ds games currently.
As for snood - my bestbuy has literally 20+ copies of it so it isnt that rare in my area at least currently.
To be honest I have found that kim possible is somewhat rare in my area its not exactly a budget game in the same manner as like ford racing 3 or space invaders yet it seems to be harder to find than both of those games.
I'd say kim possible is probably one of the "rarest" new releases - thats not to say its rare, its just the "rarest" in my area of DS games that came out in the last 3 months.
I did pickup spongebob today though for 20 bucks at bestbuy, that puts me at 89/92 DS games
Only lacking:
-harry potter (lol waiting a long time for it)
-madden 06 (waiting till a big price drop as well)
-Kim possible (this will be my next target aside from games that come out next week - i'll prolly get kim possible if I can find it for 20 dollars new)
