The 6th gen is the 128-bit era, this is the time of the ps2, xbox, game cube and sega dreamcast, there was apperintly another console called the XaviXPort but i never heard of it. This era ended arounf 2005 when the xbox 360 came out.
An often overlooked Resident Evil game for the PS2. It was in many ways the precursor to Resident Evil 4, sharing a similar camera & control system.
The only shortcoming is that the game is short, but if you like RE4 it's well worth checking out.
