Gradius!

I had forgotten about Gradius. I played so much back in the NES/SNES days...

In playing through the levels, we were surprised at how completely faithful the gameplay was. The changes are almost entirely cosmetic and the main difference is that the 3D opens up a few new possibilities in enemy movement, but that's the main extent of it.

Another reason the PS2 is now calling my name. And check out this sexy video of the game play. Of course if it was Life Force for PS2, I'd already own one...
