I was tempted to get that game for the soundtrack CD, but I don't really have the money for that right now because I actually didn't plan to buy a 3DS. Instead, I was going to buy an original DS, but after watching E3 and seeing games like Luigi's Mansion 2, Super Mario 3D, Mario Kart 3DS, and Kid Icarus, I knew I wouldn't be able to resist buying a 3DS when those games hit. So I then started thinking, why should I buy a DS if I'm just going to get a 3DS at the end of the year? It is expensive, but I don't anticipate a price drop soon and so I'd end up spending more anyway if I got a DS first. I've already bought a few DS games that I found on sale so you could say I got one to play DS games.
Too bad I've already downloaded ExciteBike 3D and Pokédex 3D before I linked my account. If I remember rightly, surveys will only appear for games you buy after you link your account to the shop, is that correct?
