You might be impressed playing Crysis 1 on consoles as well, but would you prefer playing it with realistic graphics at PC or deteriorated graphics at a console (low resolution, reduced detalization, no anti-aliasing, etc.) (http://www.youtube.com/watch?v=AcKLjgWl7tM)?

It is insufficient for serveral years already. Consoles were not improved for 6 years, and constanly developing desktop keeps getting console graphics (excluding only Crysis 1), except better resoultion, framerates and minor improvements if any.

I would find it boring to play Crysis 1 with deteriorated graphics at xbox 360 (reduced detalization, low resolution, etc.): http://www.youtube.com/watch?v=r-ksKadt5Fc

Here is more general paradox of time travelling than I met before. Consider someone who clearly remembers that he didn't receive any messages from the future in 2000 year, i. e. the universe in 2000 year doesn't have an event of receiving a message from the future. Now he invents time messenger and sends the message to himself in 2000 year. That makes a universe in 2000 year having the message from the future. So in 2000 year the universe has message from the future and doesn't at the same time. Impossible. This applies to any influences to the past.
