Agreed. And seeing that there are so many PC exclusive games, you are shunning a wide audience. Here are some that will never show up or atleast for quite some time.
Elder Scrolls Online
Command and Conquer (Reboot)
Company of Heroes 2
Starcraft II: Heart of the Swarm
Total War: Rome II
World of Warplanes
Sins of a Solar Empire
and on and on
I don't buy a technical issue. I build sites for a living as a web developer. Rather more that the folks at Avsforum have bought the hype that PC gaming is dead. I am pretty sure that games like the ones listed above or those in the past like WoW, Crysis 1, Minecraft (until it was finally ported) and so on prove it otherwise.
Every game has its place. MarioKart rocks on nintendos (upcoming release), sports games own on consoles, and so on.
I think the knee jerk reaction is that PC are always ahead of consoles in terms of image quality, but this is only the case if the pc is a strong build. Where the real advantage in pc gaming lies is in the storage capacity and access to online content. A game like Sins of a Solar empire really couldn't be played on a console because of its memory requirements. Crysis 2 showed how much had to be scaled back to accommodate the scope of terrain in the original on the PC. Games like minecraft are still much better on the PC received updates beforehand and allow heavy modification. PC game modification is another area that makes PCs stand out.
There is a reason IGN has reviews on PC games. The genre is alive and actually prospering with the advent of so many online titles. Heck, I spent way to much time last month playing this World of Tanks that my 16 year old son told me everyone in high school is playing on their PCs.
I think you underestimate how much excluding PC games hurts your reputation. Gamers are passionate people, and I like many others on here take this as a slight. Maybe you should just close down the HTPC section as well.
