Dynasty Warriors 6 - (skip to 1:25 for the fighting)
This game was the initial inspiration for me to concept a game based on addictive odds. Your god amazing character vs. vast amounts of enemies that dont stand a chance.
Although very samey there is a wide selection of playable characters, each with a different weapon and fighting style as well as a level system whereby you can upgrade your character with even more over powered goodness.
Enslaved: Odyssey to the West -
A game yet to be released, but its one I have my eyes fixed on. For me the visuals are brilliant, im not a huge fan of realism games at the moment but this one is saved through its stylized character anatomy (which is what I love in art) and vivid colours.
The fighting in this game is a style id like to harness for my project, in particular the melee combat seen at 0:17 seconds in.
Naruto: Ultimate Ninja Storm - (Was the best video for showcasing the final moves)
This fighter has by far the most amazing special moves i have seen to date in a fighting game. Its well scripted animated moves like this that i feel add intensity to a playable characters arsenal. Its the kind of situation where you sit back and just watch in awe as you finish off your foe in the most over the top way possible. Love it.
The Lord of the Rings Video Games - (Action at 0:35)
The LotR games were surprisingly addictive to me, they were a very basic hack n slash format with little else to do, yet they felt very sturdy and satisfying.
You got a great feel for the blows and and blocks as you fended off and ploughed your way through endless scores of Orcs, Goblins and Trolls. They were multiplayer, which was great for trying to out kill your friend in the final scores.
Left 4 Dead - Survival Mode -
For anyone who has Played L4D you will hopefully agree with me when I say that it is definitely one of the most addictive games ever.
Random zombie (infected) spawn locations made the gameplay unpredictable each time you played through a level. This in turn added great replay value for the some what short yet satisfying campaigns. The Survival mode which was later added, helped to further replay value by pitting you and your team against increasing waves of infected.
You have the option to set up as best you can at the start and from then on survive as long as possible for the highest score. This I find to be a winning combination and something that my game will focus on the most.
A survival mechanic vs. A score board.
**EDIT**
I had completely forgotten about this game, which is crazy considering 'Spartan: Total warrior' features an arena mode whereby you fend off waves of increasing enemies.
This video shows a short clip of that mode.
