The future of PC Gaming doesn't lie in now popular shooters. PC Gaming is alive and well, but its future, as far as financial prosperity, is being determined by MMOs, RTS, and the many upcoming indie games you can find everywhere. My faith for shooters and similar games lies in companies like DICE, Valve, and Tripwire... and I think we will continue to have a fair variety of good shooters, but its not the biggest piece of the pie.
The future also lies deep within our long time modding community, which is why more demands need to be made for editors. All the way back to Half-Life and up to Oblivion and Crysis, the modding community is what makes the greatest innovative difference for PC gamers. That is actually what I am most displeased at with C2, being unsure that it will ever have an editor released.
