Find it in your bargain bin? Do someone a favor. Buy the game, then destroy it. Actually no, just flat out smash it.
I said something about replay value. This game has none. You can play this game for five hours straight. By then, you've unlocked everything. After that there's nothing to do. No point in continuing. Zero replay value.
I got lucky with this one. When I bought this game full price back when I was like 12 years old, I sold it to gamestop, and the resale price was $20 surprisingly. The only good thing I ever got from this game was the cool poster, though I wish It could have just said "Dragonball Z" without the Taiketsu slapped under the logo. Which is another thing. This game is a cheap cash in on the DBZ franchise. You'll play much better fighting games on the GBA, which also have the DBZ logo slapped on the cover. Dragonball Z: Supersonic Warriors is literally maybe five times better than this game, and that's an understatement.
Do someone a favor. Should you find this game, buy it, then smash it with a hammer. The gameplay is bad, the sound effects are terrible, and the visuals are total ass. Don't even play it.
