This is one of those cruelly tantalising PC Engine games, always on sale for cheap, but unplayable without Japanese literacy. So when a translation patch recently came out, I was very interested to see how the game actually plays. It totally surpassed my expectations! Not only is it a game that's had a lot of thought put into every part of it, but also it feels miraculous that they could have fit so much stuff into a tiny little HuCard!
The game starts with a little cutscene, where your friend has let you drive his car, and some other guy challenges you to a race at the traffic lights. After he beats you, he tells you about the world of drag racing (or Zero Yon, as it's apparently called in Japan?), and that becomes your new obsession. But you don't know anything about it! So you've got to start by looking in magazines to find out when and where races happen, and you've got to look mechanics up in the phone book to find one who'll tune your car for racing. Then when you find one, you've got to really be persistant in convincing him to work with you! It sounds like a weird, annoying nuisance, but it really makes the game's world feel bigger and more real.
Another thing adding to the realism is that, as a new racer starting at the bottom of the rankings, it'll be quite some time before you win a race, let alone win races consistently, and when you do, the prize money at this level is a pittance, a token amount. So you've got to go to part time jobs between races. This is a section that really amazed me with how much they fit into this game! There are two jobs: working at an arcade, or being a security guard at a spooky building at night. They both pay the same (and inexplicably, your wages go up as your racer rank does), but the arcade lets you play a primitive little racing minigame or try to win a plushy from the UFO catcher, while the security job is a little minigame in itself.
When you take the security job, you're presented with a first person view of a corridor, with eight doors lining it. You've got ninety degree turning and blobber movement, and your job is to just look inside all eight rooms. But sometimes, there'll be a thief in the room, and you'll have to fight them in a little turn-based RPG battle in which you can use magic for some reason! (Though the best strategy is to just spam attack.) There's no negative consequence for losing these battles, but your boss gives you a hefty bonus for winning them! It does feel a little repetitive, having to grind for cash in these jobs do get your car to a level at which you'll have a chance in the races, but I think it's a clever bit of ludonarrative resonance: you're working crappy jobs and scraping by, waiting until you break through as a great drag racer and start raking in cash with your skills.
The races themselves are very idiosyncratic, too. Because they're drag races, there's no steering or braking to be done. Instead, you hold one button to accelerate, and you hold the other and use the d-pad to change gears. So the path to victory lies in timing your gear changes just right so you can accelerate faster than your opponent. Sometimes, you can overcome an opponent in a faster car by being more skilled than them. Conversely, sometimes, you're just completely outclassed, and a significantly more powerful car will leave you behind no matter what. The really interesting part of this is that you'll get used to how your car speeds up, the exact optimum speed at which you should change gears for the best results, then when you upgrade, you'll have to re-learn it.
I've really enjoyed this game, and I think there's a lot of potential in it that's curtailed a little by it being a HuCard game. I see online that it spawned a whole bunch of sequels, though, from the PC Engine CD, all the way up to the Playstation 2, so I hope some of those get translated at some point in the future. I don't know what's introduced in the later games, but I think the biggest weakness of this one is that there's no character to any of your opponents. In the illegal nighttime races, they're only referred to by the car they drive, and in the official daytime races, they're only referred to by their ranking number. It'd be really cool if they were actual characters, with the possibility to develop friendships, rivalries, and maybe even romances.
Obviously, I recommend giving Zero4 Champ a try, even if the subject matter doesn't particularly appeal to you. It's really got me hooked, and I can see myself continuing to play it for quite some time.
