Ahhh Doom. The current Collectors Edition with very slight tweaking works perfectly under Windows 7 64-bit on a Core i7 just FYI

I've bought Doom easily five times already... most recently I bought the 360 XBLA re-release. It still plays great. But then again, when I started playing Doom in earnest I had plenty else to draw my attention away... specifically, Quake, Duke Nukem 3D and Descent.
It's quite interesting that although all these games are quite old now - even the original Quake is now sixteen years old - they still play fantastically well. And since there's people like us who still actively want to play them, all of them have modified versions of their engines available to allow use on modern hardware. I haven't looked into Doom 'cause the current Doom95 engine from id works, but Quake has DirectQ (Direct3D based and VERY fast), Duke has eDuke32 and Descent has D1X-Rebirth.
Still, nothing like firing up the real deal and enjoying it the way it was... it's almost the bare metal versus virtualization argument

Just the local Commodore hobo and middle-aged PC hoarder.
eisa on Trademe. A lasting reminder of a Compaq fetish when I was younger.
