6th post gets it.
Valve only did a quick port to consoles to drum up cash. There are still video interviews with Chet and how he said their plan was to support the console versions alongside the PC version with updates, possibly even cross-platform play. That was a big fat lie.
Bugs, clunky controls, framerate issues, people who wanted to party together were split up in the lobby, connection issues, etc. Valve never updated the game once they threw it out the door. A huge black mark against Valve, and such a fall from the good graces of Left4Dead, The Orange Box, and the Portal games console ports which were all very good.
I think if Valve released CS:GO in its current form on nextgen consoles, it would do really well - imo would even give CoD a run for it's money if advertised enough. It would definitely have a long standing community online. But that will never happen.
