Two of the biggest games of the year have finally arrived and they could not be more different.
GTA IV takes the gamer on a bloody odyssey
For the Playstation 3 and Xbox 360, Grand Theft Auto 4 is the latest in the hugely successful crime series. Nintendo's Wii receives another innovative peripheral in the shape of the balance board for use with its new title, Wii Fit.
"They are targeting very different audiences, GTA 4 is targeting adult audiences, probably what you would consider the more traditional gamer, whereas Wii Fit is aimed at the mass market, a family audience, probably somebody who would hope to do something less sedentary than just sitting down all of the time," said Phil Elliott, editor of GamesIndustry.biz.
Developers Rockstar Games's latest third-person crime caper, GTA IV, unleashes Niko Bellic on the streets of Liberty City, a barely disguised New York.
Niko must steal cars, rob banks, take out rival criminals and generally cause chaos on the streets of this enormous metropolis.
Liberty City is roughly the size of the real New York and the level of detail and the sheer scope of the game are breathtaking.
The GTA series embodies the so-called sandbox genre, in which players can explore or perform missions in any order they like.
Like GTA games of old, Niko can steal any vehicle the player takes a fancy to, from sports cars and SUVs to speedboats and helicopters.
Next-gen upgrades include improved visuals a completely new physics engine, online multiplayer and, weirdly, a mobile phone.
Niko uses the phone and internet cafes to receive information on upcoming missions or to help maintain his relationships with his criminal cohorts. The phone can also be used to invite associates out for drink, which leads to the onscreen characters' drunken stumbling.
Rockstar have re-created New York in great detail
But all of this detail is icing on the cake, the real depth in this game is found in its gameplay. Fans of previous titles will be familiar with the formula of car chases, shootouts and general larceny.
While this latest remains true to its roots, the game has been refined and honed to such a degree that it makes most other third-person action titles seem hollow and empty in comparison.
Due to the Grand Theft Auto series themes of criminality and violence, these games have always been controversial, attracting the attention of politicians and the media alike.
However industry observers like Neil Long, editor of MCV magazine, are keen to point out the games' adults-only 18-age rating.
He said: "There are a million films out there that are a lot more graphic in terms of violence. Like any other kind of adult content, video games are just another form of entertainment.
"The people that make these kind of statements, perhaps they don't understand videogames and how they as an art form have matured. It is an entertainment form to rival movies, music and TV and it should be considered in that way."
Despite the controversy surrounding this series, 70 million copies of the GTA games have been sold worldwide. As a result, sales expectations for this latest version are high, and Mr Long believes there could also be a knock-on effect for Sony and Microsoft.
"Primarily it will push hardware sales up through the roof on the two formats it's on. Microsoft have been very keen to own this launch in terms of putting a lot of marketing out there and cutting the price of Xbox, Microsoft's message is, 'Get GTA IV for £200'.
"But at the same time GTA is often considered a very Playstation friendly series of games and it will be interesting to see which console benefits the most out of the title."
Wii Fit is being promoted for its healthy benefits
In stark contrast, Nintendo's Wii Fit is an entirely different sort of game. With the help of the balance board, players complete a number of different exercises ranging from yoga to hula-hoop spinning. Most of the exercises simply require the player to replicate instructions, which are provided via the onscreen virtual fitness trainer. The addition of the balance board with this title pushes its cost up to a UK retail price of £70.
The success of the Wii and its motion sensitive controller has seen Nintendo's games appeal to entirely new markets and this fitness peripheral could further add to the Wii's appeal.
Mr Long said: "Nintendo's strategy is very much to bring non-gamers into the industry. Their ethos for a couple of years now is the gamer market is finite; there are 10 times more non-gamers than there are existing gamers.
"That's kind of Nintendo's mission at the moment and Wii Fit is very much an element of that."
Nintendo's Wii is the biggest selling console of this generation, but supply problems and a lack of compelling third-party titles could see a significant slow-down in the machine's meteoric rise.
Phil Elliot, editor for GamesIndustry.biz, thinks Wii Fit could help weather out poor third-party support.
He said: "Wii Fit for Nintendo is the title that will respike and nudge the sales of the console back up again.
"As we have seen with the Xbox 360, Microsoft have had a really good way of putting out key tittles throughout the life cycle of this console."
He added: "Wii fit will probably be the most important title for them of 2008 and crucially it is at a higher price point as well so it will be an interesting marker to see if people are prepared to pay the higher price point, and also how many people are interested in a fitness-based video game."
So the biggest video games showdown of the year looks set to be played out between a game that endorses wholesale mayhem, and a title that encourages wholesome keep fit.
