I'll just add to the already mentioned MX518 answers. I've had mine for years now and it still works flawlessly. If the G400 or G400s works the same or better, get it. There is no going wrong with this mouse.
Well, I remember veeeery little of this game, I was too young to bother reading the names of the games. It was for the PS1, I only really remember that it was something like a 2D isometric shooter game, and when you killed enemies, you walked over the blood pools on the ground, your footsteps where blood for a small amount of time. And the loading screen was writter a big, red "PLEASE WAIT", wich was dripping blood from it... Sorry for the crappy info, I really hope you guys can help me :D
