I'll post a pic.
Here are my first Japanese PlayStation One games;
All Japan Pro-Wrestling: Soul of the King (Left, top half is back of sleeve),
New Japan Pro-Wrestling: Toukon Retsuden 3 (top-right),
Fire Pro-Wrestling G (bottom-right).
Soul of the King has some of the best character models I've seen in a PS1 wrestling game. It uses the WWF Attitude style of plastering a picture of the real wrestler on the character model, but it looks so much better.
The Toukon Retsuden engine has made numerous appearances in the States as the driving force of the WWF/WWE Smackdown games. Also worth noting is that an old U.S. PS1 wrestling game called Power Move Pro-Wrestling was a generic port of the first Toukon Retsuden game (hence the NJPW copyright on the title screen). This game features the Steiner Brothers, Eddie Guerrero as Black Tiger II, "He Who Shall Not Be Named", and n.W.o. Japan (Chono, Great Muta, etc.).
Fire Pro-Wrestling G was more of a novelty pick-up than a serious buy for the gameplay. I mainly bought it because it's a game I've wanted since I was a kid. The graphics are nowhere near what they are in D or Returns. Still, though, it's another fun game in the series and I'm glad I got it.
