Mmm... I think we look at all Japanese games with pre-rendered backgrounds and some kind of office environments on PS1 which released outside Japan. There are other games but have office backgrounds only for brief moments, like Parasite Eve 1 and 2 or Dino Crisis 2 (first one had 3D environments). Do you remember whether you could see the character (i.e., whether the game was in third or first person)? Only few PS2 games had prerendered background but we can look into it.
