Yep, that's pretty weak.
To be honest, I thought the preinstalled game was pretty sweet on the Master System 2. Come to think of it, I thought 3D was cool on the Master System.
Sega, always 25 years ahead of nintendo. We've got about 10 years before Nintendo handhelds come with a VMU.
But seriously, I kind of like preinstalled games. I especially like hunting retro systems not knowing if it has Alex Kidd or Sonic. And desperately hoping it has Sonic (even though the cart is ~$2). I think it would be neat down the road to find a 3DS with Fire Emblem, Mario Kart, etc. Adds to the hunt.
