Atom's point that PCs can be and are game systems is well taken. I honestly think that my resistance to the idea comes from the notion that there is a measurable culture gap between people who enjoy console games and people who enjoy PC games. Not to generalize unnecessarily, but a guy who's played La Pucelle is not also likely to be a guy who's played City of Heroes. Yes, there's definitely a lot of overlap, but the division is where the majority of the conversation would take us.
To the point that this is a tech forum and not a gaming forum, my counter argument is this: Would the modification of cars be off-topic? They have computers, and sometimes game consoles in them as well. How about the hacking of DVR units, or telephones or burglar alarms? This is definitely a tech forum, but from the perspective of those who enjoy video games. We may not discuss the actual act of gaming here, but I would argue that the motivation for gathering our technical knowledge is based mostly on improving or sustaining our enjoyment of our games. Although I would be very interested to hear from anybody who enjoys modifying game consoles but has never ever actually played a console game... Like maybe that guy in Sweden who bought all those VMU's but doesn't own a Dreamcast?
I wil say this to wrap up though... Lawrence, this is your field, and you own the ball and the bat. If you want to put up a new forum, do what you like. You don't need our blessing or our written permission to do anything around here, but I'm sure you already feel that way. :)
-KKC, who wonders when the Tomb Raider series became a tactical stealth game...
