Eh I bought it on release day and really only played if for about a week. Me and my roommate unlocked everyone and its pretty decent. The only "adventure" mode is in Konoha village and it's pretty simplistic compared to other games like Naruto on the 360. The VS mode is a lot of fun and very fast paced but it gets old really quick. I can play fighting games like Tekken all day long but I get burned out on Ninja Storm after maybe 10-15 fights. It really does feel like your playing the anime if that makes sense.
TL:DR - Very fun for a while, no real adventure mode, feels like the anime. (Wait to buy till it's cheap Smile
