The Jaws: Retro edition game is a pretty cool way to re-release retro games
What they did was re-release the NES Jaws game, but also included a "enhanced edition" of the NES version. They added new enemies, multiple stages, quests you can tackle to upgrade your gear and basically enhanced the depth and playtime for what was a pretty basic game.
Now, you can like or dislike the Jaws NES game, (I like it), but reworking and adding content to a classic rom is a very cool way for companies to tackle retro releases and I wish more companies would take this approach.
