I had a couple of their sports games on the N64 :D
All-Star Baseball 2001, I had not the slightest idea how to play it. Then I had an American Football game by them too, same series, I think. I couldn't even get past the kick off. (Not HVS's fault, by the way I seriously had no clue how to play Football)
I always though the "Danger High Voltage" logo was an actual warning. Eh heh, I wasn't the brightest kid.
I had Lego racers on the GBA, I don't think HVS had a hand in it, though. --- Derpy: Signal me dijo. Mey: en su firma pone eso n_n
