I purchased the Preview disc over at EB for 10 bucks + tax. I also hear its available at Target for the same price.
All i have to say is WOW!!!!!!
The Viewtiful Joe demo is well worth the money.
Just the Demo of the game is one of my fave titles on the GCN...AND its only a 2 level demo.
Its gameplay (in the DEMO) is easy enough for anyone to pick up and play, but difficult to master (you are graded on style, combo attacks, time, defense, etc.) Joe's different attacks include: high and low punch and kicks with three modes: standard, slow, Fast Forward. Throughout the Demo they make GOOD use of Joe's special abilities in order to kill enemies. Because of its simple gameplay and addictive fun, Viewtiful Joe feels like the "Super Mario" for this Generation; in terms of a game that ANYONE can play and really have fun while doing so. Not to mention that the art style of the game is just O.O
HIGHLY RECOMMENDED!!!!! Go get this Preview Disc NOW!!!!!
