The clue is in the part of the description you linked to:
Upon completion of the race (In version 1.0 the opposing truck would never move)
you would be declared the winner. Hardly a mighty achievement if the opposing truck stood still!
Also the Engrish feel of the phrase is funny.
I should emphasize that (in my experience at least) there's nothing malicious or critical about the way people find these things "funny". Rather, it's the sheer delight that comes from the sudden surprise of something being done in an unusual way. It's related to the effect experienced when someone learning a language "invents" a phrase that's perfectly logical but not idiomatic, i.e., "we don't say it like that around here". With Engrish the effect is doubled or exponentially increased, because the surprise is two-fold: "that's not grammatical, and even if it was, we wouldn't say it like that around here!".
Often, too, the intended meaning remains crystal clear, which somehow adds further to the delight. My first encounter with Engrish was the now-legendary All Your Base phenomenon. For anyone not familiar with this, it's worth reproducing some text I found describing it on the allyourbase website a while back:
Basically, a very good Sega Genesis game titled "Zero Wing" (a side
scrolling sci-fi shoot 'em up ported from an arcade game) fell victim
to poorly translated subtitles for the opening cinema.
A (human?) spaceship is exploding because (per the mechanic) "somebody
set up us the bomb." An alien overlord named "Cats" appears after the
operator declares, "we get signal, main screen turn on," and Cats then
tells the Captain of the doomed ship, "you have no chance to survive,
make your time," after informing him that, "all your base are belong
(I omit here several other funny catch phrases in the interest of
brevity) The captain, in final desperation, orders the launch of his
fighters, called "Zigs," blessing the pilots with his words of
confidence, "you what you doing, take off every Zig. For great
justice." When you start playing, you pilot your Zig away from the
final explosion of your mother-ship.
