It's a very good game. You should play it. It is kinda similar to DMC combos, but a lot of the combos are easily executed because there are 2 melee attack buttons. Some of the moves are similar to Dante's moves, one of Bayonetta attacks are similar to Dante's Stinger, except that it can be executed on air. There are even secret 'Verses' like DMC series of Secret Missions. All of Bayonetta's weapons have names. The storyline is easy to understand, but some parts of it you need to read in the internet or other sources. The game is really good, and I give it a score of 9.5/10.0.
Voice actors will decide whether they will be credited in a game or not, some of the voice actors are in a union, or non-union. If a union, the voice actors will be properly credited. If non-union, they can choose whether they are credited or not, but oftenly they will use fake names to be credited. So it is their choice whether they want to be credited or not.
Platinum Games are developers of Bayonetta, and the mebers of the developers are popular people who have worked with Capcom before, so DMC references are not avoidable, but appreciated.
Among the members of Platinum Games are:
Shinji Mikami - The man behind of Biohazard (Resident Evil) series. The director of Resident Evil 4, God Hand, Dino Crisis, Resident Evil, and Resident Evil Remake. Also the executive producer of Viewtiful Joe, Resident Evil 0, Dino Crisis 2, and of course Devil May Cry. Producer of Resident Evil Code: Veronica and Resident Evil 3: Nemesis, game producer of Resident Evil 2 and advisor for Onimusha: Warlords.
Atsushi Inaba - Former CEO of Clover Studios, and later works with Platinum Games. Best known for his work in Viewtiful Joe series, God Hand, and Mad World.
Masami Ueda - One of the main composers of Resident Evil series, and also composed the first Devil May Cry soundtrack. He also the main composer of Bayonetta soundtrack.
Hideki Kamiya - The man behind the first Devil May Cry game. He is the director of Devil May Cry, Resident Evil, Okami, and Bayonetta.
With all these guys working on Bayonetta, especially Hideki Kamiya and Shinji Mikami, why is it strange that there are some references of Devil May Cry in the game, or used DMC lines? We as DMC gamers should be proud at least that there are games took some of DMC lines or stuffs, which may be because of DMC series popularity. If you think Bayonetta is a rip off of DMC or a lame female version of Devil May Cry, don't bother playing it. Play other games. Otherwise, try and playing it.
