Should I get Brain Age 2?

By no means am I a casual gamer. I just have less and less time to play games. Furthermore, I don't want to buy Mario Kart b/c I've played it to death on my friend's Ds. I am still unsure about FFXII: Reverent Wings, not to mention its price tag is a real turn-off. But, I want 5+ games next year (looking really good year for DS gaming!) and Advanced Wars 2, coming out in less than a month, is on the top of my list. So.......should I get the more-casual Brain Age 2 to hold me over? Is only $20, right? What do you guys think?

NO!!

I bought it a while ago. I figured i would play it for 30 mins every once in a while and then put it down. I "played" it 3 times, and then put it down. Haven't played it since.

I mean, its only $20,i can go back to it. It just had the unfortunate fallback of me buying it right before i got Guitar hero 3 and Mario Galaxy.
