Take Metal Gear Solid on the GBC for instance-it does the Metal Gear name justice. Sure, I understand there are certain technological limitations that prevent a game like THPS from being ported over intact, but I'd like to think there's some innovative way around (at least some of) these limitations. I didn't, and I have a gut feeling any experienced gamer will feel the same way.
Maybe kids who don't really play games much, or are just learning how to play, will enjoy the simplicity found in this title. Dumbing down big-name games from other systems to the Game Boy must be some sort of standard procedure with game companies.
