I second "Batman: Arkham Asylum" and the "Mighty Morphin Power Rangers: The Movie" game. The latter was easy as all hell, but it was awesome! I also enjoyed the fighting game for the Sega simply titled "Mighty Morphin Power Rangers."

"Ghostbusters" the Video Game is another favorite of mine. It continues the story, pays tribute to what came before it, and the actors even returned to do the voices. Having Alyssa Milano added to the mix didn't hurt either.

"X-Men 2: Clone Wars" for the Genesis is another personal favorite. Best X-Men game in my mind, but "X-Men Legends" is a close second. The "Deadpool" game is now added to my list of favorites as well. It was just hilarious.

"Buffy the Vampire Slayer: Wrath of the Darkhul King" is another one. It used to be Chaos Bleed, but over time that game kinda gets old. "Wrath of the Darkhul King" stays fun for me. I love both "Knights of the Old Republic" games, too. Throw "Sailor Moon: Another Story," and "Lord of the Rings: Return of the King" into that bin as well.
