I'm sure we've all bought Namco's previous Museum Pieces from PS1 - Xbox, so the format is far from original. However, I would have hoped that Namco could have stretched to more than 7 games as featured in this DS collection. You can extend this to 9 but the extra 2 are merely revisions of Dig Dug II and Xevious which are already included in the initial 7 line-up.
The screen display options are smart and of the 6 options available I'm sure there is one that'll suit you. However, to play them in their true original ratio involves using the DS in 'book form' which proves difficult for the likes of Galaga and Galaxian where the use of some buttons force you to require extra limbs!
Overall, a good effort and I'm sure a sequel is on the way. Personally I would have preferred another 10 or so games to make this an essential buy. Where's Pole Position????? :)
