There is a reason you don't see more games like Castlevania and Metroid on the market. Griptonite has done an admirable job of bringing the Metroid style to Spider-Man, and have even crafted a decent game in the process. Unfortunately, when it comes to combat, enemy diversity and overall length, Web of Shadows pales in comparison to the titles that inspired it. Still, if you are a fan of Spider-Man or "Castleroid" style exploration, Spider-Man: Web of Shadows may be worth a look. It's polished and fun for the four or five hours it lasts. Hopefully Griptonite takes this solid foundation and really expands on it in a future Spider-Man title.
