oh, the mario games are good IMO...but we know those by now.
Many of the other ports indeed arent that good...
and now something else...remember pocky & rocky on snes (kikikaikai)? They made a new version of the game on GBA, but oddly enough it's a port from the original arcade version, not from the snes versions, and it's actually looking WORSE than the snes!
Also, I've looked at Gradius Galaxies and while it's nice to see a new gradius it's just not what it could have been....it's a bit of a dissapointment after playing Gradius Gaiden, arguably the best gradius ever made (allthough i never played gradius 4).
