“Classic” Xbox version had frame rate problems - but it was (i think) one of the best-looking titles released for that console. In fact, my first completed append to HL2 was on Xbox. I still remember Ravenholm, when i had damaged one of pad’s analogs.
Now I’m using modified (usb, just changed plug and installed XBCD) Xbox Controller ‘S’ with my PC. Don’t know why, but the gameplay is sightly better for me with this pad.
