It's great that they took the original gameplay of Wonder Boy/Adventure Island and updated the graphics, music, and added new weapons.
Adventure Island 2 could have accomplished this, but the game is too long for its own good... I think New Adventure Island hit a good balance... although maybe it is on the short side. Regardless, the game kicks ass for having some of the most addicting gameplay available on the VC. The 1-Hit and you die mechanic, combined with the fast-paced structure of the levels makes pretty much everyone a speed-runner :) Unlike Mario and Sonic game, which require you to slow down (either to find secrets or to progress), just about every level can be beaten with no stops!
